Every time I go to play a dos game or open a dos program a box comes up that is titled,16 bit MS-DOS Subsystem, then inside it says, C:\DOCUM~1\Joshua\Desktop\dnukem3d\INSTALL.PIF
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 Should I do? Please help. I am running Windows XP. Thanks for any help. My e-mail is [email protected]. Thanks
