Are you running with an admin account or a standard/limited account?

Are all components of VFP9 SP2 properly installed? Any reliance on 3rd party ActiveXs etc which may need to be installed, registered etc?

Does your app expect any files/folders/network mapped drives etc to be present?

Does your app work with any environment variables that may not be present?

Not responding messages sometimes are caused by too much disk I/O or a disk hardware or driver issue. Are any errors or warnings present in the System or Application event logs? Are there any other foreground apps or background services that might be causing a lot of disk I/O, maybe a backup program, File History etc? If you go into Task Manager/Performance tab while your app hangs, is there any indication of high disk or CPU utilization?

If you're using an antivirus program that's not Windows Defender (built-in), can you temporarily turn off its real-time scanning component(s) and retry?
