Hello, Just did a fresh install of P3DV5 and adding all of my FSDT addons.
I usually start with GSX and then go from there with adding airports. After downloading and installing GSX when loading the sim and trying to activate GSX, I get a warning that the couatl is not running and it gives the suggestion to exclude the Addon Manager from the antivirus (which I always do anyway). So I exit the sim and attempt the Live update. The program opens and then immediately closes, does not go through the normal update process I remember with the Live Updater. Open the sim and same issue when trying to activate GSX - couatl not running. Try Live Updater again with same issue - closes almost immediately. So, I checked that the Addon Manager was in fact excluded which it is. Un-installed GSX and Addon Manager, Restart windows, and turned off the Firewall to redownload and install. Same result. Tried with a different product (KCLT and then KORD), all are the same problem - seems to install fine but then when I go to activate I get the error about couatl and when I try Live Update same issue with it closing right away. One thing that may be worth noting - I think I remember that during the install process the installer would usually automatically run the Live Updater at the end, I did notice it try to do this (with KCLT and KORD) but it also seemed like the Live Updater wasn't working during the install process, let alone when I attempt to run it using the desktop shortcut.
Looking for guidance. Haven't tried it with any other product, I just figured I wouldn't bother going down the list and trying to install them all if its a Live Update or couatl issue as I would probably get the same result.
Thank You,
