Update 126.96.36.199: Update for Windows 8. Assemblies did not change, only the project template did.
Update: 188.8.131.52: Reduced the depth of the installation path for VSIX packages, that was causing issues on some systems (path too long). The only change is in the installer and the VSIX. If you were able to install correctly, no need to install this version.
Update: 184.108.40.206 corrects a small issue with the binaries on new projects on Windows 8 (WinRT) only.
The issue with the installer is fixed, sorry for the problems folks
