I received news about the new update (v2.2) and its new feature allowing a third cargo door for aircraft and proceeded to install the new update from the download from GSX's website. I am using FSX and I have been battling this issue as well. After the install, during my first session of FSX, GSX worked flawlessly and I fiddled around with the new feature. On the next FSX run, the GSX and coautl context menus were missing from the Add-on menu.
My troubleshooting so far, in sequential order:
- Checked FSX's 'Trusted' section to see if coautl.exe and bglmanx.dll are present and this was true.
- Uninstalled and reinstalled FSUIPC to see if the issue was caused by FSUIPC.
- Deleted all entries associated with GSX in FSX.cfg and then uninstalled and reinstalled GSX.
- Rebooted my PC.
- Uninstalled GSX since the problem still persists.
- Made a decision to roll back to version 1.9 and this gave me no issues but at this point it was too late to go back as I was now missing the new feature (mentioned above) that I got fond of already.
- Decided to use FSDT Live Update to update GSX rather than the installer downloaded from the website.
- After all this, the problem still persists.
