Microsoft Excel 97 may return the following error message when using DAO 3.5, if an application created with Visual Basic 5.0 that uses DAO is installed.

Back to the top

If Microsoft Excel 97 is installed after an application created with Microsoft Visual Basic 5.0 that uses DAO is installed, Excel does not add the DAO design-time licensing key. This licensing key is required by Excel, but is not required by applications created with Visual Basic.

NOTE: The same licensing key is also required and added by Visual Basic 5.0. Because Visual Basic adds the same DAO design-time licensing key required by Excel, the problem does not occur if Visual Basic is installed.

To resolve this problem, add the DAO design-time licensing key to the Registry. Note that you should back up the Registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.
