As I've said, never mind if it doesn't work the first time. Try a reboot, launch FSX, if you see the error, allow it to run, exit and try again. It will disappear.
I understand and I would have not posted here if I had not already tried it a few times.
But after reading your post I DID try it once more, got the error, allowed it to run, CTD. I rebooted, tried it again, same result.
As your dll.xml clearly shows, you have several modules installed. It's the modules that can create this kind of conflicts. However, for the solution, see above.
If you still see the error, try disabling the antivirus OR (better) try excluding the FSX main folder from scanning. And, after having done this, reinstall the Addon Manager, because your antivirus MIGHT have blocked it at install time, so you don't have the correct version yet.
My free copy of macafee ran out and I uninstalled it long ago. I have NO antivirus software currently (stupid I know). But I went into control panel, made sure windows defender was disabled, and windows firewall disabled. I then re downloaded the latest addon manager and ran that. I got the newest versions of the software.
Upon starting FSX same error, I said yes. CTD. I rebooted, re ran FSX, CTD again.
I understand your frustrated from having to deal with this issue as every machine is different, trust me I know I work over at LDS and we had the same issues with FSX/vista..etc.
Please if you ave ANY ideas I am open to try anything and help you and I solve this issue, which may in turn help others.
