We're upgrading our corporate remote users to 15.10 and ran across a wall. We were successful in upgrading from v12 to v15.2 since it promted for admin credentials prior to the install. Now that option is no longer available when upgrading to 15.10. Only 2 option it gives is to login with admin rights or start TeamViewer with admin credentials. Has anyone been successful performing the upgrade remotely without the 2 options?
