On a Windows XP machine all patched, I had previously installed Access 97 with Office 2000 Pro. Could not double click to open a database, but can open access and open the the database from there. Error message I receive is "The command line you used to start Microsoft Access contains an option that Microsoft Access does not recognize" Exit and restart Microsoft Access using valid command-line options. If you click on that a couple of times this error comes up, "Microsoft Access can't find the database file c:\documents.mdb make sure you entered the correct path and filename" I uninstall Access 97 and 2000 and reinstall 2000 only same problem, upgraded to Office XP, same problem. Help!!!!
