Shell and Wait - 32 bit and 64 bit

[Aflatoon]

The 32-bit and 64-bit versions of Office programs aren’t compatible, so you can’t install both on the same computer.

FYI, you can in fact have both 32 and 64bit Office on the same computer, just not of the same version. So you can have say 32 bit 2010 and 64 bit 2016, but not 32 and 64bit of 2010.
