win,msi: correct installation path registry keys

Since install is per machine only, installation path should be stored
in local machine instead of current user. The registry stores HKLM in
different places for 32 and 64 bit applications, so the installer will
not suggest the old path when upgrading from 32 to 64 bit version.

Fixes #5592
Fixes #25087
