Help with France VFR scenery

Have an issue here with the flight meditterannee scenery and the flight alpes autogen packs. When I click the start button to start the installation process, I get an error.
Here is a screenshot from the flight alpes autogen pack installation (error is the same for flight meditterannee autogen, but obviously a different file is involved.)

Help from anyone here is greatly appreciated. Pointless me asking the people over at france vfr as well...the whole forum is in french
