CloD doesn't start any more :(

[Foo'bar]

Some moments ago I experienced that CloD doesn't start any more. I doubleclick the icon, the steam status changes to "Ingame Il-2 Cliffs..." and a few seconds later it alters back to blue "online". Obviously nothing more happens.

Before all was fine. Some hours ago I had trouble with my .NET framework as the regularly updates didn't work so I decided to remove the complete dotNet to make a clean installation afterwards. Unfortunately I didn't manage to reinstall the dotNet thingy yet.

Are there any dependencies between steam/launcher and .NET? RO and RO2 starting via steam though.

Some other ideas why the launcher doesnt start?

Thanks in advance.

edit:
Problem solved. msi installer has been repaired, NET framework installer newly. But the most important: CloD is running again
