We have UAC enabled in a very secure area and it is blocking the deployment of anything that is not a hotfix. What is happening is there is a popup asking if you want the file to make changes to your system. If you click OK the .exe runs fine. When automating no one is there to acknowledge the popup. We have tried all of the various switches to create a silent install but nothing works. So far the only thing we have done successfully is create a response file for each deployment. With UAC enabled there is only one account that is not affected. The system account. We are currently trying to configure the user or user.local account to map using the system account but we have had no luck so far.
