I recently got a new computer at work.
It's running Windows 7 Professional with Service Pack 1 (same as the old one). System type: 64-bit Operating System.
When I run the installer, I get a Security Warning about an Unknown Publisher. If I tell it to Run (or if I run it in Admin mode) I get another error dialog that states:
"The version of this file is not compatible with the version of Windows you're running. Check your computer's system information to see whether you need and x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher."
Is there another version of the installer that I can try? I downloaded this one from the purchase page. When I look at my order history, it tries to download the same installer.
FWIW, I also have Fences 2, and was getting the exact same errors. I just assumed it wasn't working because it's ancient and unsupported, so I bought Fences 3...but it fails in the exact same way.
