After updating to Windows XP Service Pack 2, when I try to install ANSYS I get the following message:
"The system file is not suitable for running MS-DOS and Microsoft Windows applications."
What's going on?

For some reason the installation of SP2 can cause a file called "AUTOEXEC.NT" to be corrupted or deleted. This file is part of the Windows 16-bit subsystem and usually lives in the SYSTEM32 folder. The setup for ANSYS uses InstallSheild, which is a 16-bit program. Since the AUTOEXEC.NT file is missing, it can't run the install program. Fortunately, there is a backup of the file on your hard drive. Double click "My Computer", then your hard drive (C:) and open the "WINDOWS" folder. Open "SYSTEM32" and see if the "AUTOEXEC.NT" file is in there. Chances are it isn't. If it is, then it's probably corrupt. Arrow up or hit "Back" to return to the main WINDOWS folder. Go down to "REPAIR" and double click. You should find "AUTOEXEC.NT" and "CONFIG.NT" in there. Copy these files (Ctrl+C) then go back to SYSTEM32 and paste them there (Ctrl+V). It will ask you if you want to replace the old one`click "Yes". Now try installing that program and it should work fine. If this doesn't work, check the Microsoft web page for additional fixes. <a target=_blank href="http://support.microsoft.com/default.aspx?scid=kb;en-us;324767&Product=winxp">http://support.microsoft.com/default.aspx?scid=kb;en-us;324767&Product=winxp</a>http://support.microsoft.com/default.aspx?scid=kb;en-us;324767&Product=winxp |
