When i goto run and type command.com or goto c:\windows\system32\command.com i get the message COMMAND.COM IS NOT A VALID WIN32 APPLICATION. it only does this on 1 of the 3 xp computers. I need to run a dos program but I keep getting this error (it works on the other 2 xp computers). Please help.
 
Try using CMD.EXE on the Run line.

Command.Com is not used in Windows XP.

CMD.EXE works ok but when i try to run my program i get the ...is not a valid win32 application. the same program works on the other 2 xp systems but not mine. I can run command.com on the other 2 systems(looks like cmd.exe), but not min

note cmd says microsoft windows xp and shows a "dos prompt" with long filenames and command.com says microsoft windows dos and shows a "dos prompt" but with 8.3 filename abbreviations, so there is a difference
I went to microsoft support (kb314106) and it said something about ntvdm subsystem, checked config.nt and autoexec.nt, but I wasn't sure about the "examine the ntvdm system files" part, it says to make sure they are the correct version by checking the time and date but what time and date should they be??
 
After you use CMD.EXE, type CD\ and hit Enter to put you in the Root
directory.
Then try your Dos program.
Most of the older Dos programs will run just fine.

Hi!
Have you tried running your DOS program in the Windows 95 Compatibility
Mode?
 
Yes i have tried all of the compatability modes with no luck, it seems like something is wrong with ntvdm or it's setup
