I think it needs some explanation How to update a TB Portable installation to beta or aurora.

I tried to change the preferences in about:config: update.channel to aurora but that had no effect.

Then I edited

ThunderbirdPortable3\App\thunderbird\defaults\pref\channel-prefs.js

and restarted TB. There I got the message in the Help screen, that I am on update channel aurora, which seems fine. Still: the update downloaded Thunderbird 29 pre beta and tried to install but ended with the message that it couldnt be installed due to patch problems:

Das Update konnte nicht installiert werden (Patch-Anwendung fehlgeschlagen)

I tried this again with the channel "nightly" and got the same error. (On channel "beta" there seem to be no newer version than in the channel "release".)

How can I change my installation to channel aurora and update it?
