I get this all the time now. If I have to reset couatl or exit out to start a new flight I get the pop up to start as administrator constantly and cant shut it off no matter if choose yes or no. log attached.
If you CHANGED the Properties for the Couatl64_MSFS.EXE file to start As Admin, which is not how we install by default, you caused this issues by doing that, because the restarter doesn't need to start as admin ( same as Couatl64_MSFS.EXE ) so, a program that starts with no admin permissions will ask permission to start another one that *has* Admin permission, which normally shouldn't have.
So, either:
1) REMOVE the Compatibility option to start "As Admininstrator" you set to Couatl64_MSFS.EXE, so it will restored to the way we install it by default.
OR
2) ADD Compatibility option to start "As Admininstrator" to the Addon Manager\couatl64\couatl64_boot.exe program, so the message should go away.
Option #1 is the preferred one, the ONLY case if you need to use option #2 is ONLY if your regular Windows users is of limited permission, so you need to run the Couatl engine As Admin.
