New question regarding Omaha install process

Hello guys,

I would like to know if it's possible to ship (beside the update of the <app> requested, a secondary app (when needed). Or even more, make somehow the installer to ask for updates of some other appid that I will define.

Currently the Omaha installer periodically checks for updates of itself (the updater) and the Chrome browser app.

I successfully made a "hack" (so to say) that will also provide data about a secondary app, which is fed as a postinstall step. But would be nice if I could update them independently of each-other.

Is it possible by current design?

Many thanks!

What do you mean by saying `independently`?

Many thanks!

Perhaps what I will say sounds silly.

The installer created has a tag for the chrome appid.

Should I simply apply a 2nd tag (to the same meta installer) in order to enable it to ask for updates of additional appids?

Kind regards, Sebi Onofrei

Thank you. I think I got it now.

Applying a second tag to the metainstaller creates a "bundle" of two apps. The metainstaller will try installing both apps, and it will report an error if the installation of the second app fails.

As you suggested below, a registration for the second app id can be made after installing the first app. From that point on, the updater will check both app ids for updates.

Hello guys, thanks for the answers.

May anyone please tell me how to apply a second tag to the metainstaller?

I tried 2 separate commands of ApplyTag.exe, but only the last one seems to be called when running the metainstaller.

Meanwhile got it, there's a append flag that needs to be used for the second tag. Will test soon to see if works as i expect it
