[wix-users] Installing from a mapped network drive - Force it to use UNC?

On Windows a mapped drive is defined in a particular user's profile, so if the registry for the elevated user has not been configured to know about that mapped drive, it won't do any good to try and generate a UNC (without also having some way of getting the drive mapping from the other user's registry profile).  I don't know of any setting that will address this issue for you.

Quick question:

How do I set the MSI so it uses UNC instead of mapped drive when installing?  I have a custom action that copies over a config file that uses "SourceDir", but fails due to the MSI being elevated thereby not having access to mapped drive.  Is there a simple way of configuring an option somewhere to use UNC of a mapped drive?  I can't convert from mapped drive to UNC in the custom action as it's too late, the user executing it is admin and not the same user, even though I put "Impersonate='Yes'", so the function fails.
