I was trying to install a Photo Shop plug-in from a CD and when I clicked on the Install button, it got this error message "C:\WINDOWS\SYSTEM32\AUTOEXEC.NT. The system file is not suitable for running MS-DOS and Microsoft Windows applications. Choose 'Close' to terminate the application.
Months ago I successfully installed this plug-in on an earlier version of PS. I also successfully installed this plug-in on this same version of PS on my friend's laptop.
When I search my C drive for AUTOEXEC.NT, the only place it is located is in "C:\WINDOWS\repair". I copied AUTOEXEC.NT from my XP boot CD to the SYSTEM32 directory and rebooted but this didn't help. Apparently some file is damaged??? Any suggestions short of reinstalling XP greatly appreciated!
I also got the same error when I tried to run a typing program I downloaded from the Internet. I dismissed the error message at that time thinking the program wasn't compatible with XP.
