If FSX QUITS (not crash) to desktop without any error message, it's because the Addon Manager files haven't been updated entirely, so you have some mis-match between old and new versions.
This can't be caused by our installers, since they all take the most current version online, so it's not possible you would end up with mis-matched version, under normal conditions.
What might happen, instead, is that your antivirus is mistakenly blocking the download of .dll, wrongly assuming it was a threat, but is letting pass the other files, which are not executables so are not checked, and this will result in mis-matched versions, with some files updated and some not.
In this case, the correct procedure, as explained in many other threads, is:
- DOWNLOAD AND INSTALL the Stand-Alone Addon Manager for FSX, with the antivirus entirely OFF
- Configure the antivirus to exclude the following files from scanning:
YourFSXFolder\bglmanx.dll
YourFSXFolder\fsdreamteam\Couatl\couatl.exe
YourFSXFolder it's usually C:\Program Files\Microsoft Games\Microsoft Flight Simulator X, if you installed it in the default folder.
- Now you can turn the antivirus back on, and launch FSX.
- Check you are seeing BOTH the "Addon Manager" menu AND the "Couatl powered products" menu under the "Addons" menu.
If, instead, FSX is CRASHING to desktop, with an error message, it could be an entirely different issue, but then you should post the error message content, to understand what is causing it.
