I've seen this with a few other applications as well - even though the user has Admin privileges, something about the machine being joined to a domain (possibly something set by the domain of course) seems to require Run As Administrator for the installer. (At least for 12.12.2 and Betas 14.5.0, 14.5.5, 14.6.0)
On my so-equipped machine, running as a user with Admin privileges, the installer appears to run, but start menu icons are not created and the USB driver installer does not run. Re-running the installer with Run As Administrator works fine.
On a similar non-domain-joined machine the install runs as expected for an Admin-privileged user.
Probably a boundary condition as most users won't hit this, but posted as an FYI - no need for action on my account, I just have to remember to do it when I install new versions
