The guaranteed route is what dmargineau said.
However you may be able to try right clicking on the setup file, going to the compatibility tab, select "Run this program in compatibility mode for:" and select Windows XP. Then check the box at the bottom that says "Run this program as an administrator". You may get lucky. This is how I installed older versions of Logix5k that weren't officially supported.
I'd be curious to hear your results.
