As explained in many other threads, when the antivirus is defective and is mistakenly detected our software as a threat (not all antivirus programs have this bug, only some of them), you should proceed as follows:
- Download and install with the antivirus entirely TURNED OFF
- BEFORE launching FSX for the first time after the installation, configure the antivirus to ignore the following files from scanning:
YourFSXFolder\bglmanx.dll
YourFSXFolder\fsdreamteam\Couatl\Couatl.exe
- Now, you can turn the antivirus back on, and start FSX.
