[wix-users] Changing Burn registration to per-machine from BA

[Steve Dower]

Full context at http://bugs.python.org/issue25166, but the basic story 
is as follows:

We use Burn to let users choose whether to install per-user or for all 
users. If they choose per-user, they do not need to elevate. If they 
choose all users, elevation is determined automatically (by the engine? 
I didn't dig too far into this part).

However, the registration for the bundle remains per-user. So if someone 
selects the all users option, other users cannot see the bundle itself 
and cannot remove or modify it.

It seems that changing pEngineState->registration.fPerMachine to TRUE 
before planning starts would be sufficient to fix this, but I don't see 
any way to do this from the BA. (I'm also not sure what issues may arise 
due to having to detect the bundle in multiple locations, but I suspect 
those should be resolved anyway.)

Am I missing something? Is this a missing feature? Or a misfeature that 
we actually don't need?

Thanks,
Steve
