C’est expliqué en allant au lien hypertexte de l’article.

• Installez les drivers que vous trouverez sur le site de Logitech

https://download01.logi.com/web/ftp/pub/techsupport/simulation/FSX_Plugin_x86_Software.exe

• Télécharger USBEnhancedPowerManagementDisabler pour désactiver la gestion d’énergie sur les modules (cause des déconnexions)

http://uraster.com/en-us/products/usbenhancedpowermanagerdisabler.aspx

• Créez un nouveau exe.xml file pointant vers le plugin P3D et le placer dans %appdata%\Roaming\Lockheed Martin\Prepar3D v4\

Les fichier ressemble à ceci : exe.txt

Le sauvegarder en EXE.XML

• Démarrez P3D et cela devrait fonctionner. En tous cas pour moi c’est bon.

BONS VOLS !

Cela peut être utile notamment pour simuler la présence d’une des versions à l’installation d’add-on.
