[wix-users] Serious problem with FindRelatedProducts and install context

oops, meant to write AppSearch not FindRelatedProducts (brain fail)
The issue isn't per-machine vs per-user, it's per-machine upgrading
per-machine. Installing the dual-scope package, only per-user previous
installations are detected and upgraded.
When version 1.0 is installed per-machine, a subsequent install of version
2.0 does not 'see' the v1.0 installed product, and installs v 2.0 as a
fresh new product (overwriting the per-machine files if v.2.0 is installed
per-machine .. which is what I meant by "only one set of files")

Would that be an exe which passes ALLUSERS and MSIINSTALLPERUSER to
msiexec to install the MSI?
Would Burn be a candidate for that? I've never used Burn. Can Burn allow
the user to choose per-machine or per-user in a non-upgrade install? (for
an upgrade we'd want to remove the ability to choose)
