In closing, I'm seeing this as a result of Spyware.
I recently got a new computer (moving up from ME to XP). On the old computer I had some applications that loaded up fine. Yet, on the XP computer I get an error banner that says, "16 bit Windows Subsystem"
The body of the error window says, "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."
At the bottom are two buttons - Close and Ignore (Nothing happens with ignore).
Both of these programs worked fine in the earlier version. I tried the "Compatibility" function with no luck. I tried loading it without the XP 2 patch, and again after.
These are simple apps that use a setup program. I'm out of ideas...anybody else?
