I installed the new version, and this message popped up:

Your Steam License Key failed to load correctly.
Please exit this installer/application and try clicking Install or Launch again from within Steam.

But oddly, as far as I can tell, 11 Beta 1 is running. I have Windows 10.

I have a similar problem.

Starting Windows shows that message. Exiting DisplayFusion and launching it from Steam also immediately shows that message. In Steam, "DisplayFusion - License Key" appears in the DLC. In DisplayFusion->License Key, it shows a long license key and says licensed to "Steam License [etc,etc,etc]".

The "Licensed To" name matches what the website says, however my key is ever so slightly different. The program version uses '+' characters and the website shows '_' characters instead. I assume this is a base64 string, so '+' makes more sense.

Linking DisplayFusion to my online account and downloading the license did not change anything.
