Unexpected output of util:ProductSearch

[maciejtoporowicz]

Hello, I'm using the following configuration in my project for the upgrade mechanism:

    <util:ProductSearch Id="SomeId"
          UpgradeCode="e3047d4c-a684-47a2-94b9-e80f8fb78199"
          Variable="MyVersion"
          Result="version"/>
    <util:ProductSearch Id="SomeOtherId"
          UpgradeCode="e3047d4c-a684-47a2-94b9-e80f8fb78199"
          Variable="MyState"
          Result="state"/>

There's some logic in my installer that depends on these values.

Two users reported they had some issues with the upgrade process. They reported they had version N installed and then ran an upgrade to version N+1.

I checked the installation logs. I was expecting the following output:

• MyVersion=N
• MyState=5

However, in both scenarios, this is what I saw:

• MyVersion=N+1
• MyState=5

How is it possible? Do you have an idea what might have caused it? I cannot reproduce it on my machine.

I'm using WiX Toolset v3.11.

Thanks a lot!
