I have a user how is trying to use the Database Documentor feature. About half way through the analysis, she receives a Invalid Page Fault message that stating that App has cause an IPF in <unknown>. I am able to run the Database Documentor against the database in question, on my pc. So I know that it is isolated to the client pc. I have tried replacing the MSVCRT20.DLL & MSVCRT40.DLL, removed all TEMP files, no problem with available memory. When I ran Access in Safe Mode, I received the error 'MS Access executed an invalid instruction in Module <unknown>'
