Common Launcher Issues

1. VCRUNTIME140.dll not found

You are missing VC++ (2015) Redistributables. These can be downloaded directly from Microsoft:

You might need to restart your PC after installing the Redists.


2. Game not found

The AlterWare launcher doesn’t require selecting install-paths nor will you have to select what game to launch when starting it, because of this it has to be placed inside the game’s directory.

To find the game’s directory you can right-click the game in Steam → Manage → Browse local files.
Place alterware-launcher.exe in that directory and run it.
You can use right-click → Send to → Desktop to create a Shortcut.


3. “No such host is known.” or “An attempt was made to access a socket in a way forbidden by its access permissions.”


The AlterWare requires an active Internet connection to work.

  • If you are trying to play offline:
    • Launch the mod executable directly (ex. iw6-mod.exe)
  • If you have an active internet connection:
    • Make sure alterware-launcher.exe is not blocked by the firewall or your anti-virus software.
    • Make sure you are able to access master.alterware.dev in your Browser
      • If you are able to access it you should see “403 Forbidden”
      • If you aren’t able to access this page your DNS server may be having issues
