How to Fix System32 Error

1. Click your 'Start' menu, select 'All Programs,' choose 'Accessories,' click 'System Tools' and select 'Disk Cleanup.' Wait for the application to load.
2. Put a check mark next to all fields that you don't need to save files from.
3. Click 'OK' to clean up your disk. Continue to the next step only if you have a System32 error related to a program you try to run.
4. Right-click the program and click 'Properties.' Click the 'Compatibility' tab and select an operating system to run the program with compatibility for. If your program needs Windows 98 to run and doesn't run in Windows XP, Windows Vista or Windows 7, select 'Windows 98' on the compatibility list.
