I used ReSharper before, but then uninstalled it because it was using up too much memory and the WPF components all flickered on my system with RS installed.
Now I saw the new version out and decided to try it again. However, RS finishes the installation, but I don't see it anywhere under VS 2010.
I'm running Win 7 Enterprise 64 bit. I tried uninstalling/reinstalling, devenv was not running at the time of the installation. I tried rebooting. ReSharper simply won't appear in Visual Studio.
