Operating Instructions:

Turn on computer, and boot from its hard drive, choose Safe Mode Command Prompt only 
Run DIAG. You may use any of these optional switches:
/R  show programs that will Run during windows startup 
/S  show Share names and passwords 
/X  show eXtra property sheet and context menu handlers 
/I  dont show the standard information page
It is important that you boot from the machine that you are wanting information from.

The extra "Property sheets" are most likely to be found from the Display icon in the control panel. They are the extra tabs you may have such as "Plus!" or "Web" or "S3 Refresh".

The Run and Property Sheet options try to locate the files being refered to on your hard drive, and extracts the version information from the file. It uses Windows long file names to do this. If scandisk reports an error relating to long file names, (including any message indicating that the directory name is too long for MSDOS), then DIAG will not be able to locate the file and report it as missing.
