Graphs Trouble

If Graphs are Not Appearing NCSS 2007, PASS 2008, or GESS 2006 Output

The following does not apply to PASS 11 and NCSS 8 or later.

If you are experiencing problems viewing graphs in NCSS 2007, PASS 2008, or GESS 2006 or earlier (i.e. graphs do not appear in the output when they should), the problem is likely due to one or more corrupt installation files. To fix the problem, do the following:
  1. Find the following files in your C:\Windows\System32 directory Graphs32.ocx GSJPG32.DLL GSPROP32.DLL GSW32.EXE GSWAG32.DLL GSWDLL32.DLL
  2. Move each file listed above from the Windows\System32 directory to another directory of your choice or rename the files. Note, you must either move or delete the files since NCSS will not replace them unless they is not found in the Windows\System32 directory. You can accomplish this using your Windows Explorer program.
  3. Re-run the NCSS 2007 or PASS 2008 setup file and choose "repair" when prompted.
This should fix the problem.

"PASS is a great program. It does so much and is easy to use. It’s much better than the other sample size programs I’ve used—it has helped me greatly in my research."

As Statistician teaching statistics in the University, I have to say that NCSS is the tool that I have used since 1997. With all the procedures that you need for research or to make a good, informative presentation, it can be used for teaching in a university. Here in Idesem-Chile we have found it to be the best tool to support our measurement activities. I recommend this tool to make your job more enjoyable!
