Windows Error Message - MS-DOS not compatible For anyone unlucky enough to see this error message. "C:\Winnt\System32\config.nt The system file is not suitable for running MS-DOS and Microsoft Windows applications. Choose 'Close' to terminate the application." I have only had 2 people with this message. They advise me it has happened when they had older V2 software on PC, then install V2.7.9. The V2 software does not run and the error message appears, one of the people advised that Windows Un-install programs was of no help. A link to a microsoft site is listed for further information....... http://support.microsoft.com/default.aspx?scid=kb;en-us;324767 with appropriate screen grab attached. some extra info on this : it seems that either the AUTOEXEC.NT file is not present or it is not in the correct directory. some additional links supplied, if you have this error i recommend you look at all of the supplied links before doing anything http://www.abandonia.com/forum/index.php?showtopic=2534 http://www.rdpslides.com/pptfaq/FAQ00642.htm http://www.rdpslides.com/pptfaq/FAQ00642.htm hope this is of help to some of you.
