If the installer doesn't start, it's possible the problem is caused by the antivirus, that has mistakenly detected it as a threat, and blocked from starting.
- Download and install with the antivirus ENTIRELY DISABLED
- BEFORE launching FSX, configure the antivirus to exclude the following files from scanning:
YourFSXFolder\bglmanx.dll
YourFSXFolder\fsdreamteam\Couatl\Couatl.exe
"YourFSXFolder", under Steam is: C:\Program Files (x86)\Steam\SteamApps\common\FSX\
- Now you can turn your Antivirus on, and launch FSX
- Note if FSX asks permission to run the Addon Manager and the Couatl programs, reply YES to both
- When FSX loads, check if you have BOTH the "Addon Manager" and the "Couatl powered products" under the "Addons" menu.
