It works theoretically with 2010, but the installer format has changed so much since 2010 i didn't bother making it compatible.
So there are 2 solutions..
1) Download the vsix (it's a zip file ^^), extract and modify the manifest files manually, and rezip
2) Use the command line version by adding it to "external tools"
Don't know about ultimate, sorry, there's no reason it shouldn't work in there ..if someone has an idea ?
Got it running in 2015 at home now. At work though it complains about .net framework version. Also wierd since it relies on 4.5, yet at work i'm already on 4.6
