A couple of ideas:
- On the MFC error, there is a TechNote on SupportNet covering this: http://supportnet.mentor.com/reference/technotes/public/technote.cfm?id=MG577887. Essentially, if you happen to have a 'c:\MentorGraphics\win32\configurator.exe.manifest' file, deleting it will most likely resolve the problem.
- On the iCDB error: You might try creating a new WDIR directory and setting it as the first path in your WDIR environment variable. For example: C:\MentorGraphics\wdir and the resulting WDIR environment variable would be 'C:\MentorGraphics\wdir;C:\MentorGraphics\9.4PADS\SDD_HOME\standard'. Beyond that you may want to open a Service Request for further assistance.
Hope that helps.
