The GSX installer won't start

[pete_auau]

Just to add to the sound after you click the icon it sounds similar to the sound i get when i open the installer on my pc which is  the permission to run  the user  account settings in which a box appears which gives me  a option do you want this software to update the settings etc click yes or no. Maybe since you said you run  the installer as admin in which you should also get  this as well? maybe  this pop up box is in  the task bar?

After many attempts, I managed to install and run GSX Pro. Unfortunately, the joy did not last long.  It is not possible to restart the FSDT Universal Installer. It is cancelled.
The System Monitor shows that the werfault.exe file is running when the FSDT Universal Installer is cancelled.
As with all other apps, the Windows notification sound is heard after double-clicking.

I deleted the events before starting the installer. The information can be seen in the images after clicking on the installer.

It is not located in the taskbar.

My guess is that Couatl_Updater2.exe is not compatible with my framework. See the error message in the next post. My Win 11 is up to date.

Try to install the 4.x framework manually:

Thanks for the link!
The installation is rejected because it is already present. Unfortunately, frameworks cannot be uninstalled and reinstalled.

All applications run without errors on my system. All updates have been installed.

According to your log, the crash doesn't happen in our code, but Soraco library that is used to check the license, so it's likely the issue might be related to your .NET runtimes not installed, not updated, or some of the Windows updates not installed.

- Try to be sure all your Windows updates are installed, restart Windows when asked.

- Uninstall the FSDT Universal Installer from the Windows Control Panel. This will register again the Soraco libraries with the system.

- Reinstall it.

My system is up to date, as I have already mentioned several times! The framework is installed.
After following your instructions, the installer window opened successfully exactly once. After that, error 126 reappeared (Windows).

After following your instructions, the installer window opened successfully exactly once.

That seems to indicate the installer made a good job of either cleaning some settings in Windows that wasn't right, or register again the .NET libraries. So, if it only worked once, perhaps something (antivirus or something else in your system), is resetting something back.

Sometimes Windows, in trying to "help you", is causing more damage, there's an invisible service called the Windows Compatibility assistant, that sometimes decides to set some Compatibility settings for you that are not requireds. We recognize a couple of them in the installer, but there might be settings we don't know.

Does it rune ONCE, every time you reinstall the FSDT Universal Installer ?

After that, error 126 reappeared (Windows).

Please clarify, is this the same error from your previous screenshot ?

Yes, it's the same error. Error 126 .NET runtime error.

The correct window appears after many attempts to start the programme. Then it disappears again. The activation code also returns an error.
The following images show a few screenshots of my endless attempts. The first image gives me hope – but unfortunately not when I restart or enter the activation code.
Otherwise, my system is completely clean and all applications are working flawlessly. GSX is the only one causing problems.

I would like to start using GSX. What else can I do? My PC is up to date and stable.

I tried at least 10x to open the FSDT_installer. I was unsuccessful.

I have the same problem than Avio since beginning of September as well. Tried a clean reinstall of C++ and .net Framework. Did a clean reinstall of GSX, running as Admin, no firewall and antivirus. Updated Bios and GPU driver (even if it's not related). Tried with the offline installer as well. Still same opening/closing immediately of the updater main page.

Just found a way to have it working. I have created a shortcut with this path :
"C:\Program Files (x86)\Addon Manager\Couatl_Updater.exe" /SILENT /INSTALLMODE=TRUE
If I try running the .exe by itself or if I don't add the  /SILENT /INSTALLMODE=TRUE at the end of the path in my shortcut it doesn't work.

You're lucky!
It worked 2x for me, then the same error occurred again...
