I have a problem with my MS Access 2000. When I try to open it, it says it can't find a file (msjet40.dll). I can search the hard drive and the file is there - in the C:/Windows/System folder, I believe that is the correct place. I tried to repair and also have uninstalled and reinstalled Office 2000. On both the repair and the reinstall, I get numerous error messages on .dlls that did not register - all pertaining to OLE or ODBC files. The final result of both is the same - the same access error message described in the first line. The operating system is Win98SE. All other Office products open fine. Could this be a virus? Does anyone have suggestions on how to fix the problem?
