[wix-users] Bundle cache location & self-update

[Hoover, Jacob]

Bundles don't modify the state of the machine, installers do.

Also don't forget that Per-User vs Per-Machine bundles behave differently.  

What are you doing by creating a shortcut to point back to the bundle?

Also, are you doing a native or managed BA?  You might find this helpful if you are doing a native one.  https://github.com/jchoover/wix3/blob/Gfc/src/ext/BalExtension/wixstdba/WixStandardBootstrapperApplication.cpp

Subject: [wix-users] Bundle cache location & self-update

Hi

>From what I can tell, the cache location of the bundle seems to be %ProgramData%\Package Cache\{GUID} where GUID appears to be WixBundleProperties/@Id

I have a shortcut that launches the bundle using the aforementioned path and pass additional arguments to my bundle.

However, if the bundle leverages the app syndication update mechanism and is auto-updated, Burn will download the new bundle, close the old running copy and restart the new copy.

Since there's no guarantee the user will complete an action (Install, Modify, etc.) when the updated copy is launched, is it ok to update the shortcut at the end of DetectComplete? This would ensure it launches the new bundle the next time the user runs from the shortcut.

Normally I'd create/update the shortcut at the end of ApplyComplete, but that won't fire if the user exits. It's simple enough to compare the bundle registration code of the old and currently executing bundle to figure out whether I'm in this state. Unless there's a better way to determine this.
AFAIK, there's nothing to tell me that the bundle was launched as the result of an update operation.

The only alternative I think is to keep launching the old version using the shortcut, have it auto update and continue to do this until the user completes an operation that results in Engine.Apply being called and then update the shortcut.

Thanks,
Jacques
