I'm curious, are you getting an error about a missing DLL? This is what I get on 2013-era iMacs: 

Is your colleague installing the 32-bit version of 7zip? If so, is there a particular reason? (Assuming this is 64-bit Windows..)

Just to add, I'm not a fan of the idea of pulling out any pre-existing version, because then I'd want to make sure I can put the desired version back....

I see. So there could be a case where someone's installed 9.20, and even if we detect and use that, it's not sufficient to handle all the Boot Camp packages...

Oh, never mind. The .exe downloads are still installers, they just aren't MSIs.

So, it's also possible to pass /S and /D options to the current Beta (15.05) and install it in a separate place, but what I still don't like is that...

Maybe the Nullsoft installer had issues. The new installer still has the silent options, at least.

If you or your colleague know of a way that this _specific_ installation of 7-Zip could be removed from the MSI database on removal, _without_ affecting any possibly existing installs...

Or ideally, if there's a way to simply download the binary from an authoritative source in a format that's not an installer or another 7z archive...

Since I _might_ be getting a 5K iMac soon-ish, I may actually have a chance to test this. There are definitely a few cases where the installation of the MSI...
