[wix-users] Property "ClientProcessId" is missing in nested uninstall

[Hoover, Jacob]

If they are not documented, then they are internal to Windows Installer. While they may be available at times, I would not rely upon them... Because they are not documented.

The real question is, why do you care if they exist or not?  What are you trying to accomplish?

So no chance to find the reason why?

I tried it a few times again, and sometimes I get the properties passed, and sometimes not?!

IIRC, those properties are not documented by the Windows Installer.

Hello!

I chained a msi in my custom burn bootstrapper. If I do a MajorUpgrade (Schedule="afterInstallExecute"), I always got the following arguments via command line in my old uninstalling msi:

...
Aktion gestartet um 16:08:46: RemoveExistingProducts.
...
Command Line: UPGRADINGPRODUCTCODE={A1212C08-B8D4-4486-A5C4-474E5945F403} CLIENTPROCESSID=968 CLIENTUILEVEL=3 MSICLIENTUSESEXTERNALUI=1 REMOVE=ALL ...

Suddenly, since the last version I built, I don't get the properties "CLIENTPROCESSID" and "MSICLIENTUSESEXTERNALUI" anymore.

What could be the reason? I checked everything, I just added a few files to the msi, nothing else?!

Desperate me.
