My operating system is Windows XP is it safe to attempt to install a program whose system requirements are: Windows 95, 98 or Me?Celeste Stewart

Installing Programs Designed for Earlier Operating Systems
The problem with installing programs designed for earlier operating systems is that these programs were not designed for the newer operating systems due to the fact that the newer operating systems didn't exist yet. However, that's not to say that these older programs won't necessarily work with your newer operating system. That's because developers often create newer operating systems to be backwards compatible, at least for a generation or two. If you where attempting to install a Windows 95 program on Windows 7, it's doubtful that Windows 7 will support it.

Problems You May Encounter When Installing Pre-Windows XP Programs
Because pre-Windows XP programs are not designed for that operating system, it's possible that the programs won't run, won't display properly, or will generate error messages. The program may expect a different data format or it may be set to look for specific Windows files or folders that are no longer present in Windows XP.

Windows XP Compatibility Features
Windows XP, along with newer operating systems such as Windows Vista and Windows 7, has some built-in compatibility fixes and modes that address some compatibility issues between applications and the newer operating system. According to Microsoft TechNet, when Windows XP was originally released, it came with a database containing about 200 compatibility fixes as well as several compatibility modes. For end-users, there's the Compatibility tab and the Compatibility Wizard.

For example, after installing a program, you can right-click the program's executable file (the file that's used to launch the program, typically ending in .exe) and choose Properties. From there, you'll find the Compatibility tab where there's an option to choose which operating system the program should emulate when using the program. Find the Compatibility Mode section and place a checkmark in the box next to "Run this program in compatibility mode for." Then use the dropdown box to select the appropriate operating system. Similarly, you can go to the Windows Help and Support Center and find the Compatibility Wizard which will walk you through assigning compatibility modes for your programs.

So, if you have a legitimate program that worked well for you on earlier operating systems, there's a chance that Windows XP will be able to run it and it's not inherently dangerous to try. Good luck!
