The error, You must be logged in with administrator permission to update the integration module may occur when you try to run the QuickBooks Integration Manager for Web TimeSheet. The user who is trying to run the integration manager should have administrator access on both Web TimeSheet and QuickBooks.

The error is thrown because integration manager is trying to download an update available on the internet. Whenever there is an update available for QuickBooks Integration Manager (QBI), it will automatically be downloaded when you launch the integration module. You may not have the necessary permission on your computer to download and install programs or applications, or there could be a group policy on your network which is not allowing you to download the update for the QuickBooks Integration manager.

A user with administrative rights on the computer should launch the QuickBooks Integration manager/module to allow it to download and install the update and then you will be able to use it without any problem, or your System Administrator has to assign you the required permission to download and install the available update onto your computer.
