When using Crystal XI, the Access database file (the file generated by the RE/EE/FE export) is locked and is unable to be updated/overwritten while Crystal XI is still open.  Please make sure of the following:
 
  1. If anybody has the report open within RE/EE/FE, 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 ReportA.MDB, ReportB.rpt uses ReportB.MDB).
  4. 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, click Database, Log On or Off Server, Current Connections, select the MDB file and click on Log Off.

If the above steps do not resolve the issue, the following is a work-around:
     
    • In the custom report parameters, click the Click to edit export icon to the right of the Select Export field
       
    • The export parameters open. Select File, Save As.
       
    • Enter a new name for the export
       
    • Click Save
       
    • Save and close the custom report (export parameters)
       
    • Open the custom report in the Crystal Reports application
       
    • Use the Set Location to link the report to the new exported file (.mdb) created in step #3
       
    • Save and close the report
       
    • Re-open the custom report in The Raiser's Edge (export parameters)
       
    • Ensure that the Refresh Export checkbox option is marked
       
    • Click Print or Preview to run the report
