Thread: can't open borland C

everytime i want to open my borland c ver 3.0
it comes out like this

16 bit MS-DOS Subsytem
C:\DOCUME~1\Andy\Desktop\BC.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.


i've tried to reinstall my borland c, but it's useless.
i've tried to find AUTOEXEC.NT. but none.
is there any sugestion?
thx for the reply
