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

[Christopher Painter]

Does Windows Installer still have a team?  Do they have a road map?    It's hard to imagine them doing anything these days that would break it.  Any breakage that could occur could be anywhere documented or not.

Yep. This is why we say the things we say about undocumented properties. Don't use them. They may or may not break you in the future.

Ok. Thank you guys.

I need to know, if my msi was getting started by a bootstrapper or standalone. If started from a bootstrapper, I need the process id of the bootstrapper to get the user token of this process so I can impersonate the user later (for accessing network shares and stuff). This is not recommended, I know and I simply can pass an argument from my bootstrapper to my msi rather than using "CLIENTPROCESSID" and "MSICLIENTUSESEXTERNALUI". Since a few months, I've never had a problem using these properties and I thought, it's an good idea to use these ones, rather than creating them again. Also I appreciated, that these properties were getting passed to the nested uninstall. Anyways. I'll stop using them and instead pass my own property to the msi.

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.
