@jndiwjdwd Depending on how your company / group policy is setup, a user on the machine must remain an admin through the entire update process. This can be done either using an admin user or elevating the standard user to admin, then running the update.
As an Admin user: complete the update / reboot / LITERALLY WAIT 5-10min after logging back in (ie walk away and don't touch keyboard), then launch QB to see if the update succeeded. If it does, log out / log in as the standard user and check QB again.
As the Standard User: Try elevating the user to Administrator group (can do through elevated Computer Management console or Control Panel - Users) / log out / log in / then install the update / reboot / again WAIT 5-10min and check QB again (the user should remain as an admin through this entire process).
