The Bugbug bot thinks this bug should belong to the 'Core::Security: PSM' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Please make sure you do not enable Compatibility Mode.

Please make sure you do not enable Compatibility Mode.

I know nothing about "Compatibility Mode". Is this a common setting? Are we going to see a wave of install failures with the Windows 7 deprecation due to this setting?

I mean Windows Compatibility Mode.

This has nothing to do with compatability mode. The offline installer was downloaded from https://www.mozilla.org/en-US/firefox/all/#product-desktop-release and then right clicked and "Run As Administrator" was selected.

I am retracting this report. The problem was that applocker was blocking SYSTEM.DLL from executing since it was under AppData. Somehow my rule that allows administrators to run all DLL's was deleted.
