QBWin.log error: LVL_ERROR—Returning NULL QBWinInstance Handle

Legacy KB ID: 3863

Question

I get the following error in the QBWin.log file:  LVL_ERROR--Returning NULL QBWinInstance Handle.  What do I need to do to correct it?

Answer

This message indicates that Verify Data was unable to complete.

Solution

1. Rebuild Data twice in a row

2. Verify data again (it will probably show that there is data damage).  Now the QBWin.log will show new errors that will be useful in troubleshooting the data damage.

3. If this does not resolve your issue refer to the following document for rebuilding your datafile:
