Why didn't AutoElevate prompt for a request?
Common reasons why AutoElevate may not prompt.
Please ensure that the Agent for that specific computer is set to "Live" mode, and the User Account Control (UAC) is configured to prompt.
Additionally, it's worth noting that not all installers trigger the UAC prompt, especially those that install into the local user area rather than Program Files. AE is designed to respond to the UAC appropriately without disrupting regular workflow.
