When I did the first install, a Explorer windows popped up and asked me to point to the FSX folder, i.e. the GSX installer could not find the FSX folder by itself
This because you had your registry key entry for FSX wrong or pointing to the wrong folder.
My FSX is installed on drive D and till now no other Addon had problems in finding the correct FSX location.
There might be two different registry keys for FSX, one under the HKEY_LOCAL_MACHINE key, and one under the HKEY_CURRENT_USER key. The proper key that should be used by a proper installer that conforms to MS UAC (Windows Vista and above) directives, is the key under HKEY_CURRENT_USER, and our installers use that one.
Other installers, made following Windows XP rules, might use the old keys and, if the correct new key on your system is wrong, but the legacy one is right, an installer using the legacy key might find FSX in that case, so you can be mislead thinking it's all fine with your install ( it isn't ) and there must be a problem with the installer ( there isn't )
After that the installation process worked w/o problems.
Of course. As you might have noticed, our installer proposed to *browse* the FSX folder for the correct path, once it found that your proper (non-legacy) registry key was missing so, after browsing for it, it FIXED IT for you, so now your two registry keys should be finally in agreement.
I started FSX but no message like "do you trust this addon" appeared
You don't say *which* addon. There are two modules you must trust, Addon Manager and Couatl.
After that I did a complete unistall followed by a new install of GSX, the antivir was deactivated. Now the installer didn't ask for the FSX location, but when I start FSX I cant see GSX. Btw: the couatl.exe does not appear in the task manager whe FSX runs. What do i wrong?
If you did just that, you haven't followed the correct procedure to the letter:
- Go into Control Panel, Uninstall GSX and reply YES to the questions "Do you want to remove the Addon Manager ?" and reply YES to the question "Do you want to remove the Couatl script engine ?"
- TURN YOUR ANTIVIRUS OFF.
With the antivirus still disabled, reinstall GSX
- BEFORE launching FSX, configure the antivirus to exclude the following files from scanning:
YourFSXFolder\bglmanx.dll
YourFSXFolder\fsdreamteam\Couatl\Couatl.exe
- Now you can turn your Antivirus on, and launch FSX
- Note if FSX asks permission to run the Addon Manager and the Couatl programs, reply YES to both
- When FSX loads, check if you have BOTH the "Addon Manager" and the "Couatl powered products" under the "Addons" menu.
If still doesn't work, be sure you are NOT running FSX into any of the "Compatibility" modes under Vista/Win7 ( right-click on FSX.EXE, select "Properties", select "Compatibility" and be sure NOTHING is enabled in that page)
If still doesn't work, maybe you also have inadvertently Un-trusted us as a Publisher, so nothing signed by us will run.
To fix this, go to the Control Panel, under "Internet Options", look for the "Content" tab, there should be a "Publishers" button, that will list the software publishers that you trusted, and another tab with untrusted publishers. If you see "Virtuali s.a.s", remove it from both tabs (especially if it's under untrusted)
