FRC 2015 Update Suite won't install on 64-bit Windows?

[cbf]

After downloading and unzip'ing the FRC 2015 Update Suite (https://decibel.ni.com/content/docs/DOC-34731), when I double-click on setup.exe on a 64-bit Windows 7 system I get an error:

"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 an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher."

Hard to believe that the release won't work on 64-bit systems. Was this just a bad stub setup.exe done at the last minute (it's only 1Kb!)?
