Commented Unassigned: Install X2goClient.exe [226]

Hello,

I'm french admin in a company and i want to deploy X2go client on computers.
I created an update that contains the .exe with the option / S for silent installation.
On my test client, X2go installs correctly and it works!
The problem is that in windows update there is always: Code 80070643 Installation failed ..
The update never disappears from the client computer ... even though I reinstalled the update over still the same error ..

Have you any idea?
Thank you very much!
Comments: Re-bonjour, Tout d'abord merci pour votre aide. OK je vais essayer de trouver la listes des codes de retours si possible. Par contre je n'est rien mis en regle "Isinstalled" car il faut entrer le code MSI mais le fichier se présente sous forme d'EXE...
