Do you have .NET 4 installed?

Yes, I have 4.52

Hang tight.. going to be publishing a new build that reverts back to .NET 3.5 in a bit since it's disagreeing with so many installs out there.

Auto-update to build 12215.1277, please.

Please roll back to version 2.14 build 1105.1380:

I'll be moving the new changes to a beta installer for us to try and get to the bottom of these issues with. The most recent updates have been removed from auto-update, so you should be able to just install this version over your current install without any issues.

Thank you
