Popup dos window 'C:\program' is not recognized as an internal command"

May 31, 2005 3 Replies

I notices something on my new xp computer, then when I open certain AutoCAD drawings, I get a slew(a dozen?) of blank pop up DOS command windows(c:WINDOWS\SYSTEM32\cmd.exe), with a message 'C:\program' is not recognized as an internal command, operable program or batch file. They popup and disappear in a matter or a few seconds. Just curious why that happens.


Check your system path and user path environment variables. It looks like some kind of script or addon you're using is trying to execute a batch command of some sort (presumably located in "Program Files"), but can't parse long file names and didn't include the quote marks.

But taking into account your previous post... I would say you have something strange running on your system or just a really funky AutoCAD addon.

Delete anything that is directed to your Project Files Search Path.
