I probably did get the patch version wrong. Sorry for any confusion.
Since this game implements no form of copy protection, I doubt StarForce or something nasty has been installed.
I checked for StarForce, so I know that's not the problem. I was just giving it as an example of why I get very suspicious when an installer asks me to reboot.
Install programs almost always ask you to reboot, even when you really don't have to.
Like I said, I honestly can't remember the last time a game installer asked me to reboot, let alone a patch!
Did you install the .NET framework so you could use Galaxy Forge? Or was it already installed? Just trying to help

As far as I'm aware, it was already installed, but perhaps the patch updates it?
And you're right that my shutdown problems could be a coincidence. All I know is that my computer shutdown fine, then I installed the game, installed the patch, and now I have shutdown problems, so who knows.
