When my computer (Windows XP) boots up on my network, a window pops up saying “Window install” followed by another window that says “starting sonic activation module.” Then it comes up to install disk - disk not found. I have to cancel out of this about 3 times before I get to where I want to. Help?
Windows Install - Starting Sonic Activation Module
This problem is particularly prevalent with Dell computers though other computers also suffer the occasional Sonic Activation Module error as well. Two potential solutions exist. The first involves cleaning up with the Windows Installer Cleanup utility while a related problem involves downloading a Sonic Update Manager hotfix. If you have recently uninstalled Roxio software, the Windows Installer Cleanup utility should do the trick.
Sonic Activation Module
Sonic products, including Roxio products such as MyDVD, Record Now, Toast, Easy Media Creator, and DVDit, feature an installer program known as the Sonic Activation Module. When Sonic programs have been uninstalled, the “starting Sonic Activation Module” error often appears. This is because the Windows uninstall utility does not adequately uninstall the software. While the program in question may have been uninstalled, leftover components remain, including the Sonic Activation Module. Since you are not trying to install the Sonic software, the disk not found error pops up because obviously, you have not inserted the Sonic software disc.
Windows Installer Cleanup utility
Solving the Starting the Sonic Activation Module Error. In order to solve this annoying startup error, you will need to uninstall the remaining Sonic components. First, download the Windows Installer Cleanup utility from Microsoft. This utility cleans up partially installed programs on your computer and helps with failed uninstalls. Next, install the cleanup utility and launch it. Find and remove any recently uninstalled Sonic utilities in the list.
Related Sonic Update Manager Problem
Similar to the starting Sonic Activation Module error at startup is the “insert Sonic Update Manager Disk” error at startup. Sonic has issued a hotfix that solves this particular error. Download and activate the hotfix and your Sonic Update Manager Disk error should disappear.
As you may know, uninstalling programs using the Add and Remove Programs utility in Windows isn’t a perfect process. Files get left behind and occasional errors appear as a result. For future software removals, consider using an uninstall product such as Perfect Uninstaller.
