I thought I was pretty clear and concise in my message
No, you weren't. You said you installed with the antivirus off, which is not enough, which is why I added the information that you MIGHT need that WAS missing from your post.
Furthermore. I have configured my anti virus to exclude the above. It was my oversight not to mention that in the original thread
That's what I meant...
however it does seem I am not the only one experiencing this issue and a fix is needed.
Your issue doesn't even have anything to do with this thread, which is about ONE thing: FSX closing/crashing when the new Addon Manager is installed while, according to your own report, you lost the Couatl menu with no FSX crashes.
Entirely different, and there's nothing to "fix" in both cases, I'll be able to tell you what the real cause is in your case, when'll post a clear answer.
I am not getting FSX crashes.
That's also what I've said about your report being unclear. You said: "Couatl is no longer visible in the addon's menu", so I'll repeat my question again: It's not entirely clear from your message, if the Couatl menu disappears at a certain point while FSX is running, or it doesn't even start. If it doesn't even start, the most likely cause is the antivirus blocking it.
I said "the most likely cause" it's the antivirus, which was an entirely legitimate answer, consider you haven't said if you HAD configured it correctly or not, you just said you installed without the antivirus.
Now, assuming it's not the antivirus, it doesn't mean that my question if Couatl disappears after a while or not even appearing is not valid anymore, since "most likely cause", doesn't mean the ONLY cause. There are other less common causes for Couatl not starting at all, but it doesn't make any sense searching for them, if you don't reply to the original question about Couatl not even starting, or disappearing after FSX starts.
Furthermore, since as I've said this thread is about FSX closing and NOT about "Couatl disappearing", by posting your issue here, you are just making this thread more confusing for everybody to follow.
So, after you checked if Couatl doesn't start or if Couatl disappears, as I've asked, please OPEN A NEW THREAD with the proper title ( "Couatl doesn't start" or "Couatl disappears" ), so other users might find it easily in the future. Do not reply here, please, because your issue doesn't have anything to do with this thread.
