@coyote2 - Got it! I'm able to reproduce your scenario if I invoke RunAsInvoker to launch MBAM. I understand the annoyance of not wanting the UAC prompt, but this does put your system in a strange state and as you can see causes problems with MBAM trying to deactivate a trial. I'm unsure if you will run into the same issue with the Elevated Task Schedule method you linked. I will report this to our developers but if you do see more issues in the future, I suggest running the program regularly or even "As Admin" as you stated.
