Confirming; it's a regression from 88580a3ad6e6afea25716b8717a33d20184154e5.

It seems that on Windows msiexec should be capable of handling either
architecture no matter which one it was launched with. This seems to be already
the case in Wine, but there are a few places that we are missing support, e.g.
MSIREG_OpenUninstallKey(). I'm working on a patch.
