I've got the same issue. I was going to try the install on the first page, but the link is no longer there. I have removed .NET framework 4, and tried to install nd still get the .NET 2 error so I'm still struggling with this.
EDIT just found a very good link. Solved it:- http://www.performancetrucks.net/for...nstall-466156/
had to download Orca so I could edit the MSI.
