Launcher not working and french error message

@Valorean, we have another update on the beta_launcher to try.

Firstly, please can you ask your friend to do the following -

  1. Ensure Steam is run without Administrator permission
    -1. Right-click the desktop Steam.exe icon
    -2. Select ‘Properties’
    -3. Select the ‘Compatability’ tab
    -4. Make sure the ‘Run this program as administrator’ checkbox is not selected
    -5. Select ‘OK’

  2. Delete the launcher folder in the Vermintide 2 directory, here:
    \SteamLibrary\steamapps\common\Warhammer Vermintide 2

  3. Open Steam and verify integrity of game files
    -1. Right-click Vermintide 2 in your Steam library sidebar
    -2. Select ‘Properties’
    -3. Select the ‘Local Files’ tab
    -4. Select the ‘Verify Integrity of Game Files’ button
    -5. When complete, close and reopen Steam

  4. Launch Vermintide 2 using the beta_launcher

Please let me know how they get on.
