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.

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.

Problem: Path Does Not Exist Error

Install Shield Problem with some Dell Laptops

With this problem irrespective of where you place the binaries for installing PyMol you receive an error claiming that the path\setup.exe does not exist.

Fix: Install the windows binary through via 16-bit MS-DOS console.

First place the PyMol setup binaries in an easy to find folder, e.g. C:\PyMol

Use the RUN command via Windows Start.

In the CLI type COMMAND.COM (note CMD will not work as it is a native interface and not true DOS).

In the DOS CLI that opens go back to the root directory C:\ using the cd.. command.

Then go to the folder into which you placed PyMol, e.g. cd PyMol.

Then type in setup.exe.

PyMol should now install, simply type exit to close the DOS CLI
