When I run the .exe I get a message that "your PC can't run this software" and to please check with the company that provided it to get a compatible version.
I installed it on my PC at home just fine. It is also running Windows 8 Pro 64-bit. Are you sure your OS is 64 bit? That sounds like an error you get when you try to install a 64 bit program on a 32 bit OS.
Make sure it fully downloaded. The first x64 version I downloaded was only 352 bytes. The second one was 92.6mb and installed properly. I'm on win7 though, not 8.

I downloaded the 32-bit version here at work so that I could update my office machine, dropped it into dropbox, logged into my home computer via RDP to run it, and was told that I needed the 64-bit version (from the iTunes installer).

I've installed iTunes 11.1 64bit without problems in Windows 8 Pro 64bit.
The only glitch so far is related with iTunes Radio: when I click on the link I get a meesage from Windows 8 telling me that it doesn't have an app that can handle "itsradio" links.
