Hi all,

I had similar, Plan-g3 looking to install .NET4 on startup. I clicked ok to install, but it did nothing. Plan-g2 runs fine. I checked to find that I too only had .NET4  CLIENT installed. I got the standalone installer as above and installed, rebooted, ran windows updater ( there were a few updates for .NET4), rebooted and now plan-g3 runs.

Mines' a Windows 7 64bit OS.

Regards,
Philip
