[wix-users] wix same version updates of package creates Duplicate Control Panel entries

[Blair Murri]

If you look in your MSI with Orca (or any other MSI inspection/editing tool) you should see UnregisterProduct, but it only runs when REMOVE=ALL, which happens when RemoveExistingProducts runs in the launched MSI (in your scenario).

Same version upgrades has always been a bit unreliable due to some weird edge cases in the way Windows Installer processes the Upgrade table (scheduling RemoveExistingProducts has no bearing on this issue). Those edge cases appear to now be baked in, as they have been there for over 20 years.

The general use case for upgrades of any kind involves a changed ProductVersion (within the significant parts) for MSI.

To see what exactly is happening, check your verbose logs around the FindRelatedProducts action (where the properties specified in the Upgrade table are set)

>From the Windows Installer perspective, all that matters is package code,
product code, product version, and upgrade code. For details, see
https://docs.microsoft.com/en-us/windows/desktop/msi/patching-and-upgrades

At first I wondered if the value of Schedule matters since I
Schedule="afterInstallInitialize" but I remember now that I have seen two
ARP entries even when AllowSameVersionUpgrades="no" if both packages have
the same product version. I wonder if this works differently if
RemoveExistingProducts is scheduled late.

From
https://docs.microsoft.com/en-us/windows/desktop/msi/registerproduct-action

"The RegisterProduct action registers the product information with the
installer and with Add/Remove Programs."

I can't find an UnregisterProduct action. How are products normally
unregistered?
