Frozen Resharper installator

Question

Im testing latest 5.0 night builds and starting from last build R# installatior has frozen. I've tried everything
- install / uninstall
- add remove programs / repair
- install previous 4.5 version
- reinstall MSXML

Still same - it hangs at the last step of installation (Uninstalling from VS or Repairing VS) Only way is killing process

What I also notoced is 3 msxml6 processes (2 system and 1 user)

So current situation is I have no "Resharper" menu in VS, its shortcuts dont work as well
Any advice ?

EDIT
- Rebooted few times
-I notoced that installers brings up devenv.exe process. When I'm killing it installer successfully finishes (but still no Resharper in VS after...)

EDIT 2
Also Installer Windows Installer CleanUp (stil same...)

Answer 1

Thanks to RS Team finally found solution.

What helped:

devenv.exe /setup
devenv.exe /resetskippkgs

Maybe helps the others..
