I have Windows XP Home SP2 installed on my IBM 390X laptop. I'm trying to install the latest version of the Datamaster software, but I keep getting a "16 bit Windows Subsystem" error message that 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." What causes this type of error message, and what can I do to fix it? It's happened with a few other programs I try to run on this computer too. BTW, the AUTOEXEC.NT file doesn't even exist in that directory.

 

Not sure why your getting that error but you can't see autoexec.nt because it's a system file.

You need to change your view to enable viewing of system/hidden files.

 

I did that already, but still couldn't find it.

EDIT: I found a copy of the AUTOEXEC.NT file on another computer, copied it over, and now it works! Thanks for the suggestion - even though I had already looked, it got me thinking again, and finally figured out a solution.
