Get your taxes done using TurboTax

I am not asking to run flawlessly.

Does TurboTax technical support want me to uninstall and reinstall as an administrator?

Does TurboTax technical support want me to simple re-register product when running as administrator even though it is a single computer?

Has TurboTax team QCd and adequately tested TurboTax installed as a non-admin user?

What are the required steps to have TurboTax Premier update as a regular user or is this not possible without throwing an error and displaying a window that can not be dismissed requiring opening windows task manager to stop TurboTax updater?
