Problems & Solutions

Problem: Installing PyMol 0.98 on WinXP Pro SP2

If you get the following error while installing

 "16-bit Windows Subsystem.":
 "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.

Fix: Sounds like the AUTOEXEC.NT file is corrupt. You can fix this problem by replacing

c:\WINDOWS\SYSTEM32\AUTOEXEC.NT

with the one in

c:\windows\repair

However if this doesn't work (or if the file is absent from this repair folder), use the file on the installation CDROM, it is

autoexec.nt_ 

in the i386 folder. Just type in a command window:

expand X:\i386\autoexec.nt_ c:\windows\system32\autoexec.nt

where X is the drive letter of your CDROM.

If this does not resolve your issue, visit this link: MS Support For This Issue where you may also find the answer to your question.


Problem: PyMol Binary Crashes

Video Driver

Fix: Try updating your video card's driver software. This is a common problem on laptops.

msvcr71.dll

Fix: find the file msvcr71.dll on your computer and copy it to the directory that PyMol was installed to.
