Solutions to troubleshoot QuickBooks Error 3645

Solution 1 – Running the Rebuild / Verify data utility

QuickBooks error 3645 occurs when the verification of data integrity fails. In that case, running the verify/rebuild data tool helps in isolating the error.

Step 1 – Checking QuickBooks company data

1. Go to Window -> Close All -> QuickBooks file section.
2. Now, choose Utilities and tap on verify data-
3. In case the verify tool doesn’t identify any data issues, then your data is clean and integrity is confirmed. You don’t have to move to the next steps.
4. Suppose any error message occurs, then search it on the QuickBooks Desktop support site to find the address.
5. If you get this message, “company data has lost integrity”, it means data is damaged and you have to rebuild it.

Step 2 – Rebuilding the QuickBooks company data file


1. Go to QuickBooks -> file tab -> choose Utilities -> Rebuild data tool.
2. QuickBooks will now ask you to make a backup before using the Rebuild Data tool. Click OK, create the backup, choose where you want to save it, and click OK again.
3. When saving the backup, don’t overwrite an old one. To avoid this, type a new name in the File name box and then click Save.
4. Choose Ok after the completion of the rebuilding process and go to the File menu.
5. Click Utilities-> choose verify data for checking any additional damage.
6. If the tool finds more problems, you’ll have to fix them yourself. To do that, look up the error in the qbwin.log file on the QuickBooks Desktop Support Site to find steps to fix it.
7. If no errors are found, you can bring back your recent backup by clicking File, then choosing Open or Restore Company.
