I have a web app that attempts to install an ActiveX control that requires admin rights. When the user I am logged in as isn't in the local Administrators group I don't get prompted for username/password and the install fails. When I put that same user in the local Administrators group I do get the prompt for a username/password and the install completes successfully. I have the following settings in a GPO applied to the computer that I am logging into."User Account Control: Behavior of the elevation prompt for administrators in Admin Approval Mode" - "Prompt for credentials""User Account Control: Behavior of the elevation prompt for standard users" - "Prompt for credentials""User Account Control: Run all administratos in Admin Approval Mode" - "Enabled"I also checked with rsop to make sure these were being applied and all looks good. Same with the event viewer... nothing is in there to suggest there is a problem. What am I missing here? TIA.

Hi I believe the application needs toinclude a manifest thatdefines an appropriate requestedExecutionLevel element. See the following page for more details.

Have you tried using the ActiveX Installer Service? It's an optional feature that you have to add in, but it allows standard users to install ActiveX controls. There is a decent doc on it here http://technet2.microsoft.com/windowsserver2008/en/library/700f3fa8-452c-4826-bdea-e76e79bee1671033.mspx?mfr=true

Yeah, I tried that as well. Nothing seemed to work. What did end up working was disabling UAC. I am going to blame this one on the application, though. It is horribly written. I can't seem to get it to install in the same place twice, it overwrites itself when it's already installed, etc... It really doesn't make much sense. UAC operates as expected in every other application I've came across except this one?!?! Oh well...
