When using Crystal XI, the Access database file (the file generated by the export) is locked and is unable to be updated/overwritten while Crystal XI is still open.  Please make sure of the following:
 
  1. If anyone has the report open within the Raiser's Edge, Education Edge, or Financial Edge, close the report and then try again.
  2. If the report is open within the Crystal reports program, close the specific report and close the Crystal Reports program and then try again.
  3. If using multiple reports with the same export file (.MDB), make the export file name unique per report (ex: ReportA.rpt uses ExportA.mdb, ReportB.rpt uses ExportB.mdb).
  4. Make sure that you have sufficient rights to the folder where the export database file is being saved.
  5. Locate and delete the associated .LDB file if possible.
  6. Open the report in Crystal. Select Database > Log On or Off Server > Current Connections. Select the .MDB file and click Log Off.
  7. If using Crystal XI and Windows 7, open the Task Manager. Select the Processes tab and end the process of any "crw32.exe" instances. .
  8. Recreate the .rpt file
