Joe,
Have a look at the MSI Automation interface - through the ProductState
property of the Installer object you can find out the installed state of an
MSI - including that it is installed for the current or a different
user. At least it might show where the install is. The WMI interface
may provide some more information as well.
You could use it as part of a bootstrap for your new install - tell the
person installing that the previous version is there and needs to be manually
uninstalled first.
When I did this I was lucky it was a server application, so I knew exactly
where it was.

(OT) Screwed up on per machine install;what should I do?
Hi guys,
This is more of a general Windows Installer issue
than a WiX issue, but I thought I'd solicit the feedback of the list as
many of you will certainly have useful opinions.
Essentially, last year when I was still quite
new with WiX and WI, I built an installer that really really should
have been per machine and should have specified ALLUSERS=1, but I didn't know
about that and got a per user install instead. The software installs an
IIS add-on and is definitely machine specific.
Now, I'm having the problems you would expect
with major upgrades and even simple uninstalls, in that only the user who
installed the software can uninstall it or detect that it is installed
properly.
What would you do? I plan to change future
versions to do per machine installs, but it would be nice if I had a way to
fix the mess I've created. This software is for internal consumption and
hasn't been installed broadly, so I have a reasonable chance of chasing down
most of the installs.
All insights are greatly
appreciated.
