Question: I just downloaded CVista PdfCompressor Professional 3.1. When I try to start up PdfCompressor, I get an error message about failing to load ‘CommonDialog’ from COMDLG32.OCX. Any ideas what is going on here?

Answer: The reason that you are getting the “failed to load common dialog from comdlg32.ocx” error is most likely because one or both particular files existed prior to our software install. To resolve this issue please follow the steps below:

1. Browse to C:\WINDOWS\system32 locate one or (you might have) both of these files “comdlg32.ocx and comdlg32.dll” and rename them (i.e. comdlg32.ocx.old and comdlg32.dll.old)
2. Uninstall our software.
3. Reinstall the software.
