Fix QBWin.log errors

Learn what to do if you see QBWin.log errors in QuickBooks Desktop.

If you see a message about rebuilding your company file, don't worry. Follow the onscreen steps and rebuild your file. When you're done, you may see additional error messages about your .log files:

• Verify Primary: Duplicate transaction number: Primary, Trans, txn#, date, doc#.
• Verify Primary: totTrans wrong. Is ### should be ###.
• Verify Primary: Next trans number is ### should be ###.
