My FSX wont start at all because of coutl.exe . I have tried to older updates but still the same result.
This because Couatl.exe is NOT the cause of FSX not starting up. Couatl.exe cannot prevent FSX from starting because, by definition, an EXTERNAL .exe cannot prevent FSX to work. If Couatl.exe would crash for any reason, the worse it can happen is that it will just disappear from the Addon menu, and that's it, it cannot cause FSX to crash or not start at all.
So, your problem of FSX not starting doesn't have anything to do with Couatl.exe
Note that, if you see some kind of error related to Couatl.exe, you might be MISLEAD thinking that Couatl.exe is the cause of FSX not starting up, but it's likely the opposite way around: the same problem that is preventing FSX to start, might AFFECT Couatl.exe the same way. Since they BOTH use the VC++ 2005 runtimes, it's possible that a corrupted/missing/badly installed runtime would affect BOTH in the same way, so FSX AND Couatl.exe are not working for the same reason, and both are victim of the same problem.
I removed your other post about this: as explained many times on the forum, DO NOT post twice about the same problem, you won't increase chances to be replied to, and you will only delay response time.
