I want to have diagnosed the problem and understood the root cause, you should go for troubleshooting. But before that there are a few important things that should be taken care of. So here they are!

• This problem is caused due to the QuickBooks installation as well. So to rectify this problem, you can simply check whether the Windows is up-to-date or not.

• Once that’s done, you can get the Quickbooks desktop updated on your desktop. 

• Once you have checked the company file folder for any missing file, and also have done the updates required, as well as your windows are updated. If none of these are lacking you must connect with an expert.

• You can also try to download the QuickBooks tool hub and use the QuickBooks file doctor to fix the QuickBooks 3371 error code.
