I am having problems installing the beta. I just converted my key to steam to see if it will work. I will update shortly
Welcome, Isn't really the place for PA beta issues. A better place would be Beta Issues & Bugs subform. There people would notice your issue and help you much faster.
For people having installer/launcher issues, first recommendation is make sure you have updated .NET 4 and .NET 4.5 installed. That shouldn't be a dependency for much longer, but with the launcher, it is currently necessary.
