Hi,
I'm not sure how to get Liberkey beta, but according to my installed Liberkey it already is 2.0.0.387
The Paint.NET program is latest when I check for updates. The error it produces is this:
When I try to install .NET again it says:
".NET Framework 4.5.2 or a later update is already installed on this computer."
edit: perhaps it checks for 4.5.2 specifically and there's already some 4.6 preview I'm now not entirely sure if that's not installed too (using shared computer)
