Here's my approach: From search in windows I located the msjet35.dll file and deleted it. Tried to open session: result was msjet35.dll file not found. O.K. Remove DB program. Check for msjet35.dll-no file, good. Reload Db program, run session,: Result: different version found!Run search in windows, find msjet.35 file, click on properties...file was created when the DB program was loaded. Worse...the msjet35.dll file version is the same version as is on the Pc's that the DB program works on?
