I'm trying to work out why I have many bglmanx65.dll crashes. I googled the problem and the advice was to uninstall one FSDT product, uninstall Addon Manager and run FSDT Live Update to install things afresh.
I uninstalled Geneva for P3D and Addon Manager. I then downloaded the FSDT Live Update but after the initial screen a progress bar appears for a couple of seconds with a mention of GSX but then disappears off the screen.
The command line for the program is:-
C:\Program Files (x86)\Addon Manager\Couatl_Updater.exe
I have another shortcut with the following command line:-
"C:\Program Files (x86)\Addon Manager\Couatl_Updater.exe" /SILENT /INSTALLMODE=TRUE
That briefly shows a startup screen but then a very different FSDT Universal Installer screen shows in graphical form. All my purchases are shown as Active but pressing "Update All" does nothing. If I select Install one of my purchased airports a message appears saying to use the standard Updater. But doing that doesn't work.
I cannot run P3D with couatl64 running as it crashes. What has gone wrong simply with me uninstalling Geneva and Addon Manager?
When I start P3D once past the Scenario Menu the error message appears and if I show the log here it is:-
couatl v5.0 (build 6019)
