Windows installer does not respect non default path names

[corch]

I just tried to use the windows installer:

Firstly, it needlessly requests elevation since plugins get installed in the user profile.

Secondly, because requests elevation, the default path it chooses is the user profile for the elevated account (don't assume the user installing has local admin, they might be using a separate admin account for elevation).

Thirdly, if you manually try to choose some other path than the default path, the installer ignores whatever you choose an installs in the admin user's profile anyway.
