Application crashes right away when starting?

This issue could occur due to two different reasons:

  1. You never installed .NET Runtime. It is included with the installer we provide, but if you canceled the installation, that would be the cause.  This can be also downloaded directly from Microsoft.
  2. You have likely installed two different versions of MSFS. The application will not run because it is looking for the correct MSFS version.  Be sure you do not have both the Microsoft and Steam edition folders on your computer as they will cause conflicts.
