Trouble with 8.0.1 installer for VS 2012+

Hello. I've got some trouble and was wondering if other people are running into the same problem.

I'm using Resharper 8.0.1 on VS 2010 since a couple of months. A while back i thought i could just install VS 2012 & VS 2013. Unfortunately when i thought i could just simply install it on 2012/2013 as well, i found out, that despite attempts to remove Resharper 8.0.1 and installing from scratch, i would not receive the newer VS as available platforms to integrate it.

Any thoughts or suggestions on how to fix this?
