Upgrade always ran as per user not per machine

[DavidStrachanLexacom]

I am fairly new to Wix and inherited an previous setup, so apologies in advance if my question is very basic.

The problem:
Upgrades are not removing previous install for some user.

Diagnostic:
I found that this was only impacting users that installed originally to the machine and not user. I setup and ran the logging and saw:
FindRelatedProducts: current install is per-user. Related install for product '{GUID}' is per-machine. Skipping...

Question:
Why is an upgrade running install per-user when the original was set per-machine?
Is this due to the upgrade not running Install, but running InstallNoShield (not elevating privileges)?
Where in the Wix Setup would the upgrade install be defined?

Additional information:
WE have MajorUpgrade set as:
<MajorUpgrade DowngradeErrorMessage="A newer version of [ProductName] is already installed. Setup will now exit."/>

Per-user/per-machine is a setting on the package. Your current package is per-user. The package already installed is per-machine. The Windows Installer will not upgrade across "install scopes".

So the real question is: Why does your package have a different install scope now?

[barnson]

The intent appears to be to let the user choose between per-machine and per-user installs. That means the user would have to pick the same scope for an upgrade to work. That's one of the reasons letting the user choose is usually a bad idea...

Thanks, my issue is that on the upgrade though that choice is negated. The system does it for them but does it incorrectly.

Ahh, so that sounds like the bug. You'd probably benefit from reading the Windows Installer documentation about the installation contexts and the ALLUSERS property. A verbose log file will probably show you what is going on.

I have a verbose log, which showed:

What else would you look for?

As I mentioned above, the ALLUSERS property is important. Watch it in the case that works and does not work.
