What is QuickBooks Error 3371?
Error 3371 appears when QuickBooks Desktop cannot load the licensing information it needs to launch or activate the application.

Register or activate software
Starting QuickBooks after installation or update

QuickBooks saves information related to your product registration. This information can cause issues that prevent the application from confirming the install.
