Error 9645

When I went to backup my QB 2017 Desktop file, I received an error message 9645 with two lines of messages below it that look like key-value pairs of integers.  It said to contact support....any ideas what to do next?

Thank for bringing this to our attention, hoekma.


There are different reasons why you  encounter the Unrecoverable error. It's possible that there are:

  • missing Windows or QuickBooks updates
  • damaged components
  • damaged data 
  • damaged user profile

First, make sure Windows and QuickBooks release are up to date.


Second, let's do the Verify and Rebuild process to get rid of any data integrity issues.


If the same error occurs, you can follow the suggested solutions in this article: Unrecoverable Error - General Troubleshooting Steps.


This article can be a good reference, too: Unrecoverable Error in QuickBooks Desktop.


Let me know how this goes so I can give you a hand if necessary. I'll be around.
