I believe you'd have to log in as each user and execute the installer as that 
user.

Subject: [WiX-users] uninstall per user product


Hi all,

I have changed the product install type from per-user to per-machine and
want to uninstall prior per-user installs. According to the archived emails
it seems I need to write an uninstall utilitiy to remove all products
installed by users. My question is "How can I find all users who installed
the prior version?"

We have used a same product id so I can detect whether the prior version is
installed or not by checking:
HLKM\Software\Microsoft\Windows\CurrentVersion\Uninstall\{productid}
However as only a user who installed the prior version can uninstall it, I
need to find a list of users who installed the prior version. Is there any
Windows Installer API that supports this kind of scenario? Any hints will be
appreciated.

Thanks,
Hyung
