sys.BUILDARCH is the value of the -arch argument to candle, which Votive sets to the Platform property of the project during build (so it will reflect the build configuration, and if you build two MSIs with the same project will probably be different values for each one). It has NOTHING to do with the bitness of the developer’s box.
var.Platform is initially set by Votive to be the value of the Platform property (but if don’t use wixtargets it won’t be set for you) and could be redefined just about anywhere in the build process, including in WXI files you may include.

Read my First Reply: $(sys.BUILDARCH) should be used when determining Build time Components on the DEVELOPER MACHINE $(var.Platform) should be used to determine the TARGET MACHINE'S bitness. Your having a tough time here because $(sys.BUILDARCH) is always equal to $(var.Platform) on the DEVELOPER MACHINE. Caveat: The above is always true unless setting the CPU Type in VS as Phil Stated.
