Vista 64 here, and it just ain't working. Install works, but when I click the shortcut on the desktop, I get an error message. I have the Net 3.5 Sp1 installed.
Something along this. The message comes in danish, and I am far from computer savvy, so...
The file or assembly "D20RulesEngine, Version=0.0.0.0. Culture=neutral. PublicKeyToken=null" or one of it's dependencies could not be read (or run). A program of the wrong format was unsuccesfully run (or read).
64 Bit definitely does not work at the moment, a developer confirmed this.

I remember we had some problems with this, too, once upon a time. I can't remember what we did exactly. Either it was a Visual Studio setting or something in the Installer itself...
