When I try to install Nokia PC Suite it displays a "connAPPI.dll files not found" error.

Nokia PC Suite and ConnAPPI.dll Files

The Nokia PC Suite is used as a means of communication between a computer and a Nokia phone. For example, the Adobe Photo Downloader uses the Nokia PC Suite to communicate with Nokia phones and download photos from the phone.

Installing Nokia PC Suite

Since this error appears when installing the Nokia PC Suite, it's possible that the installation program you have has a corrupt connAPPI.dll file. Try going to Nokia's website and downloading a fresh copy of the Nokia PC Suite software. Before you attempt the installation, go into Add and Remove Programs and remove any prior Nokia PC Suite installations if any appear.

Safe Mode Software Installation

Some software can be installed when your computer is in Safe Mode while other programs can't. If for some reason you are trying to install the Nokia PC Suite in Safe Mode, it's worth trying it in normal mode instead. The reverse may also be beneficial. If you were trying to install the software in normal mode, try installing it in Safe Mode to ensure that nothing interferes with the installation.

Update Windows

Windows Updates often include patches and DLL files for popular programs and devices. Make sure that your computer has the latest Windows updates. To update Windows, go to Start > Control Panel > Windows Update and click on Check for Updates. Your computer will download and install updates. You will need to restart your computer after.

Since the problem is occurring during installation, your best bet is to visit Nokia and download a fresh copy of the Nokia PC Suite.

The oleaut32.dll file is important and without it, your laptop won't boot up. It would be much easier to address the problem of a missing oleaut32.dll with a CD and CD drive available. However, if you can access another computer and research the necessary steps for the method you choose, you might be able to fix the missing DLL error.

Booting into Safe Mode to Get Around Startup Errors

Quite often, booting up into Safe Mode does not work on the first try. It is important to go through the motions several times in your efforts to get past the startup error and get your laptop up and running. Safe Mode does not use the oleaut32.dll, which is why you can boot up in Safe Mode even when the computer is missing the oleaut32.dll.

Replacing the Oleaut32.dll

If you can get into Safe Mode with Internet access, download the oleaut32.dll from a reputable source online. Scan the file for viruses to ensure that it is not going to put your laptop at risk. Install the oleaut32.dll file.

Creating a Bootable USB Key

Since you have access to USB ports, you can create a bootable USB key that you can use to boot up the laptop. This isn't going to be an easy or simple task since you don't have access to a bootable CD that you can copy to your USB stick. Borrow a computer from a friend to create your bootable USB key.

Windows Vista and 7 Users and the System Repair Disc

If you are fortunate to be using Windows Vista or Windows 7, it might be possible for you to repair your operating system simply by borrowing a Windows System Repair Disc and computer with both a CD drive and a USB drive. You'll need to copy the Windows System Repair Disc to your USB stick. Now comes the hard part. You need to change your laptop's boot up mode to USB drive. In order to do so, you need to get into the BIOS to switch this method of booting up. Please note that the repair disc/USB does not reinstall your operating system. It can only be used to repair it.

Unfortunately, I cannot find any information on the apsesedo.dll. I can only assume that it is a recently created or uncommonly used DLL. I can offer a few troubleshooting strategies to help you resolve this DLL error.

 DLL Errors 

Most likely, either one of the programs that you are using isn’t working properly or you have some form of malware on your computer. Try the following suggestions to see if you can resolve the problem of not being able to open sapsesedo.dll.

 Start Up with “Last Known Good Configuration” 

One of the first steps you can take is to start your computer up with its “Last Known Good Configuration.” This should allow you to use the computer with the settings it had prior to the DLL problem. Power up the computer, press the “F8” key repeatedly until the computer boots to a screen where you can select the option “Last Known Good Configuration.”

 Boot Up with Installation Disk 

If you are still having problems with DLL error messages, try booting up with the installation disk for the computer (if you have it). To do so, turn the power on, insert the installation disk into the CD drive, and hit the “F1” key on the keyboard to bring up the screen that allows you to change the boot up option to CD drive.

 Clean the Registry 

If the problem still exists, use a reliable registry cleaner such as RegCure to clean the computer’s registry in hopes of setting things right. Registry cleaners are good at repairing broken files.

 New Software Issue 

Did you recently install new software? It is possible that the software hasn’t been installed properly. Try uninstalling and reinstalling the software in hopes of fixing the DLL error.

 Scan for Spyware and Viruses 

It is possible that your computer has been infected with some type of computer virus. Use a reliable anti-virus application to scan your computer so that you can remove any infection that could be causing the problem. If you already have an anti-virus application, make sure that you up date it first before using it. If you don’t have an anti-virus application, I can recommend Anti-Virus PLUS.

What is Magendi.DLL?

Unfortunately, very little is known about the Magendi.dll file at this time. When performing a Google search for this DLL file, only one result appeared dated a few weeks ago. According to the Prevx.com "File Investigation Report" for Magendi.dll, this file is categorized as malicious and was first reported on December 5, 2010 in the United States. This really doesn't tell us much. Whether or not the file is malicious, it's hard to say based on the lack of information about this file.

What are DLL Files?

DLL files are like building blocks for software developers. Rather than creating programs completely from scratch, developers use blocks of existing code to accomplish common tasks. These blocks of code are often in the form of Dynamic Link Library (DLL) files. These files reside on your computer and whenever a program needs to run a particular function that relies on the DLL file, it runs the function by calling up the related DLL file. When the needed DLL file is missing, program errors appear. Since your DLL error loads at startup, it's likely related to one of the programs that loads at startup (which could include a malicious program that you're unaware of).

Why do DLL Files Disappear?

DLL files can disappear for any number of reasons including damage from an unexpected shutdown, the installation of new programs that replace older versions of DLLs with newer ones, and unintended deletions such as uninstalling a program and all of its "no longer needed" system files.

Restoring Windows with System Protection/Restore

If your computer has System Protection enabled, it periodically takes snapshots of the system's most important settings, including DLL files. This is one of the best ways to recover from a missing DLL file because you can rollback your system files to an earlier date in time - back when everything was functioning correctly. System Restore does not erase your data but you may need to reinstall a few programs and devices if they were installed after the restore point. You will also need to update your operating system and antivirus programs after the restore. To restore your system, go to Start > Programs > Accessories > System Tools > System Restore and follow the prompts to restore your system to an earlier point in time.

If you do not have System Protection enabled, think about any recent changes to your system or try launching programs individually to determine which program or device is generating the error. If you can figure out which program or device needs the file, reinstalling the program or device will reinstall the missing Magendi.dll file.

In many cases, missing dll files are relatively new ones when information on them cannot be discovered through a basic internet search. This could mean that the dll is part of a malware application that is trying to disguise itself or it may be part of a relatively new software application.

Missing DLL File Windowskbdsnb

It is possible that your missing dll file Windowskbdsnb is related to HP software, a virus, or some other program. If you are using HP, then the file could be a legitimate one. However, it would probably look like kdbstub instead of kbdsnb. Therefore, it is easy to imagine that this dll error might actually be related to a virus infection that was either partially removed or remains resident on your computer. A variety of malware have been know to attempt to hide themselves simply by parading around with a dll that resembles a dll from a reputable program.

OQAQUGAR DLL File Missing

A search for the OQAQUGAR DLL File brings up nothing using several different search engines. This would suggest that it is either a relatively new file or a small one that is used rarely. It is possible that the dll file has been created by a recent application that you have installed and subsequently uninstalled on the computer. Consider whether or not you have recently installed/uninstalled any programs. It could also have been created by some type of malware.

Incomplete Removal of Malware and Missing dll Files

In some cases, when malware such as spyware and viruses are removed from a computer using an anti-virus application, a trace of the application that has been removed remains on the computer. Typically, upon boot up, an error message may appear indicating that the file cannot be found. This is because the malware application has been removed, but a trace of it still remains in the computer's start up. Scan the computer with several different anti-virus/anti-spyware applications in an attempt to remove all traces of any malware that might have infected your computer.

Replace dll Files

If you believe the missing dll files are legitimate and can you pinpoint the most likely application they belong to, uninstall and reinstall the application. If all goes well, any missing dll files should be replaced upon a successful installation.

Conduct a Clean Boot Up of the Computer

One of the strategies that you can use in an attempt to resolve the problem is to perform a clean boot of your computer using the directions found at Microsoft Support.

Summary: Missing dll files can create annoying problems booting up a computer. How can you rid your computer of problems related to missing dll files?

KHEDBC.DLL Errors

There doesn't appear to be much information about khedbc.dll and its function. However, that doesn't mean you're out of luck. DLL files are system and program files known as Dynamic Library Link files. Think of DLL files like software building blocks. For example, common software functions like printing or uploading files to a server are used across multiple programs. Rather than creating these functions from scratch, developers often use DLLs. Windows computers are preloaded with hundreds of DLLs and many more are installed with other programs. Not only does this make it easier for developers to create programs, it makes the programs smaller because many of the components required are already on the users' systems.

Problems arise when DLLs disappear or become damaged. This can happen in many ways including uninstalling other programs (and agreeing to remove "shared system files"), power surges, virus attacks, and accidental deletion.

Restoring DLL Files

There are several ways to restore DLL files. In your case, since this just happened a few days ago, the easiest option is to use System Restore (if enabled). System Restore takes periodic snapshots of your system files so that should something go awry, you can restore those files. What's neat about this utility is it doesn't affect your data. It simply rolls back your system to an earlier date when all of its system files were intact. Your data files remain safe and sound. You may need to reinstall any programs installed after the restore point as well as re-update your operating system and antivirus programs.

Go to Start > Programs > Accessories > System Tools > System Restore and choose a restore point from before the problem occurred. Follow the prompts and your problem should soon be solved.

System File Checker

Another option for restoring DLL files, is the System File Checker. Because many DLL files are considered system files, this tool is often effective at restoring them. Go to Start > Run and type in: sfc /scannow  

This tool scans your system to make sure all of the system files are present and in good condition. If not, for example, if an expected DLL file is missing, the tool will replace the missing or damaged file with a clean copy. You may be prompted to insert your Windows installation disk so that the utility can copy the missing file back into place or your computer may have a hidden partition containing Windows setup files. Have your disk handy just in case.

Software and DLLs

If you recently installed or uninstalled software just before the DLL went missing, it's possible that either the new installation overwrote the DLL or the uninstall removed it. If you know which program it was, try reversing the process (either uninstalling or reinstalling).

Hopefully System Restore will be available to you and solve this pesky missing DLL file.

Since we are unsure why this type of error is occurring, you have several options that you can try to resolve the problem.

What is the corefoundation.dll?

CoreFoundation.dll is associated with Apple software, and is typically used with software belonging to iTunes, MobileMe, or QuickTime.

Reinstall the Application Asking for the CoreFoundation.dll

Quite often, the quickest way to fix a missing DLL file is to reinstall the application that needs to use it. This means that you need to completely uninstall the application and reinstall it. If the application has its own uninstaller, it is best to use that program to uninstall the program properly. When you reinstall the program, it should automatically reinstall the corefoundation.dll file. If this strategy does not work, try another one.

How to obtain a missing CoreFoundation.dll?

It is possible to download the missing DLL from a free online DLL directory. Once you download the file, you need to copy it to your "Systems" folder. Typically, your "Systems" folder should look like: C:\Windows\System 32. Once you have it, you can follow these instructions to register the corefoundation.dll.

• Select Start.
• Select Run. (In Vista and Windows7, search for "run."
• Type "cmd" into the open box that appears.
• Press enter.
• Type "regsvr32 corefoundation.dll" into the Command Prompt window.
• Press enter.
• Type "exit" in the Command Prompt window.

Scan Computer for Spyware and Virus Infections

Problems with the corefoundation.dll are often discovered after the computer has been infected with malware of some type. All types of malware including a Trojan Horse, worms, virus, and rootkits can corrupt a DLL file, leading to prompts that you are missing the DLL. Use your anti-virus/anti-spyware application to check for problems. If you don't already have one, you can use one of the free versions such as Ad Aware, AVG, SpyBot, or Hijack This. Microsoft also now offers free computer security tools.

What are DLL Files?

DLL files - also known as Dynamic Link Library files - are a format introduced by Microsoft to allow various applications to access commonly used information from shared files, referred to as shared library files. These files act as containers for data and processes that are frequently used by a number of different programs and applications so that each individual program and application doesn't have to contain the data separately. This acts as a space saving feature, reducing repetitive data and saving computer space to run processes more efficiently. DLL files are structurally the same as Windows EXE - or executable files, meaning that they are self-initiating and launch when called upon by the program, not requiring manual initiation.

What is the D3DX9.DLL File?

In your case, the d3dx9.dll file is related to DirectX components that you have installed on your computer. DirectX is another Microsoft solution that stores collections of APIs - application programming interfaces - used on various multimedia programs: games and video. DirectX and similar formats are also the foundation for the Microsoft gaming console Xbox.

About DirectX DLL Files

DirectX stores runtime libraries. Your error message means that some of these library files are missing for your multimedia files - most commonly different games. For some reason the DLL files are not always loaded with the game, assumedly because users will already have the libraries installed.

Download the Latest DirectX Version from Microsoft

Thankfully, the solution is simple. You can visit the Microsoft website and download the latest version of DirectX, or the latest updates and get your computer up to speed. This way the DLL files will be stored on your system and available to all the games and applications you run that require them. Alternatively, you can install DirectX directly to the game disk if you only want it to be available for the single application. Here is the link to the Microsoft DirectX 11 webpage.

Hope this helps!!

DLL errors are common for Windows operating systems and may be caused by corrupted programs, bad hardware or malware. DLL files (dynamic link library files) are a collection of files that allow executable programs to communicate with a device or contain code that allow the system to perform particular functions.  They are basically helper programs for the other programs that you are running on your computer.

VUMEFESA.DLL

This particular DLL error is most likely malware that was added into the registry as an auto-start so that it will load on boot up. It looks like it was attached to part of the registry that holds information for shortcuts and when it is infected by adware such as this, it can rewrite your shortcuts which is probably why it is coming up when XP is loaded. The registry stores Windows operating system setting and options including those for the hardware, operating system software and user settings.

Cleaning the Registry

Because this is malware, the best course of action is to scan for viruses and adware, clean the registry and then do another scan to be sure the system is clean. You want to make sure you don't cross contaminate and reinfect your system, which is why we recommend two cleanings.

If you are not currently using a good antivirus program (and you should be), you can check on our site for some reviews and options. If you do have one on your system, make sure you have any updates installed and then do a complete scan. Once that is done, a registry cleaner such as RegCure can clean out your registry errors. After that, do another virus scan just to make sure that nothing got duplicated and dumped back on your system.

Once you've followed those steps, the DLL error should disappear. There are ways to get into the registry and do it manually, but I don't recommend it, unless you are a tech pro, as changing the registry incorrectly can wreak havoc on your system.

Booting Past a Startup Error

If you aren't having any luck booting into Safe Mode, then booting from your Windows operating system disk is likely your only option. You will, however, need to have a Windows boot disk for almost anything at this point. Before we go on, some users with this problem report being able to boot into Safe Mode with a command prompt after several tries, so if a boot disk isn't readily available, you could try booting a few times to see if you can get on that way.

Use Recovery Console from Boot Disk

In any case, you need to get some control over your system and, if normal and safe boot procedures aren't working, there are boot disk options. First, you can use the Recovery Console to run some hard disk repair scans, which will hopefully take care of the problem.

1. Put the Windows CD in the drive and turn your computer off
2. Give it a minute, then boot back up - the computer should boot from the disk
3. At the Welcome to Set Up screen, press R for Recovery Console
4. Use the arrow keys to choose you installation, then Enter
5. If you are asked for an Administrator password, leave the field blank and press Enter
6. Now, at the command prompt, type in chkdsk /r - there is a space between the k and the /r.
7. The chkdsk application will launch and check your hard disk. It takes some time so be patient and let it run - it can take more than an hour and a half and go through periods where it appears stalled. Don't interfere, let it run .
8. When the scan is complete you will be returned to the command prompt - type exit then press Enter
9. If your computer doesn't restart automatically, shut it down and restart manually
10. I hope this boots normally to Windows

Repair your Windows Installation

If not, you can try to repair your operating system installation in a similar procedure.

1. Put the CD in the drive and reboot the computer - it will start from disk
2. At Welcome Screen press Enter to Set Up Windows
3. Accept the license
4. Choose the operating system using the arrow keys on your keyboard, then press R to launch the repair. This will keep all your files and folders in place and only reinstall the Windows programs that might be corrupted
5. Let it run, don't press any key to boot from CD even if you are offered
6. Once its finished, reboot and I hope you are back up and running
7. Now, it is VERY important that you reapply all your Windows and security patches, updates and applications

I hope this does it! If not, write us again and tell us the operating system you are using and as many details as you can about the problem and what you've tried. Good luck!
