The only procedure that works is THIS one:
- Go into Control Panel, Uninstall GSX and reply YES to the questions "Do you want to remove the Addon Manager ?" and reply YES to the question "Do you want to remove the Couatl script engine ?"
- TURN YOUR ANTIVIRUS OFF.
With the antivirus still disabled, reinstall GSX. Use the latest full GSX installer on our site.
- 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. PAY ATTENTION TO THIS.
- When FSX loads, check if you have BOTH the "Addon Manager" and the "Couatl powered products" under the "Addons" menu.
What "unblocks" the files from FSX (assuming you HAVE correctly acted on the antivirus), is the step I highlighted in bold:
reply YES to the questions "Do you want to remove the Addon Manager ?" and reply YES to the question "Do you want to remove the Couatl script engine ?"
Of course, reading your reports, it seems that you are running MORE than ONE antivirus at the same time (Norton and Malwarebytes), which is asking for trouble, and of course is a big hit on performance.
Apart for suggesting of getting rid of ALL antivirus, and chose just ONE, if you still insist running several antivirus at the same time, you must configure to exclude the affected ones in each one of them and when the instructions says "turn the antivirus off", you must turn them ALL off!
That's why is not a very good idea running several security products at once: it will quickly become very confusing using them, even not minding the huge performance loss.
