What is causing that to happen?
A bug in your antivirus (Norton, maybe ?)
When the antivirus is defective, and reports a false positive, the correct course of action is as follows:
When the antivirus is defective, and reported a false positive, you must install this way:
- 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
- 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" menus under the "Addons" menu.
