Can't re-install accidentally deleted program
 

Really hoping someone can help here...

I've accidentally deleted a program that I use a lot off my computer, (must have had a 'senior' moment). Although the software is old and no longer supported, I desperately need it back.

Didn't think this would be a problem, as I've still got the original disk. However, when I try to re-install it, the following message appears:

16 bit windows subsystem
C:\windows\system32\autoexec.ini
The system file is not suitable for running MS-DOS and Microsoft Windows applications. Chose close to terminate

If anybody can offer any advice, that would be most appreciated!

Another possibility is: rename file c:\windows\system32\autoexec.ini to something else (e.g. change "ini" to "bak"), then try it again.

Not many programs use that 16-bit subsystem any more, which means that that file may have been created and used by the very program you're trying to reinstall. If the program needs it, it will create it - but keep the .BAK file as a backup, anyway, in case anything else happens.

Thank you very much - problem is now sorted, much to my relief :)
