Build Updates

I created an installer that just included wyUpdate.exe, this would be fine only for the fact that my app is over 140MB compressed.

When I build updates from all previous versions to the latest, two 140MB files are created, e.g: xxx.all.to.1.2.370.wyu and xxx.1.0.to.1.2.370.wyu

It takes a while to upload these, so I would rather only upload the one 140MB file.

If I select build updates from version 1.1 and newer (i.e. skipping 1.0), there doesn't seem to be any info included in the wyserver.wys for v1.0 to update itself. In this situation, if wyUpdate is trying to update from v1.0, will it use xxx.all.to.1.2.370.wyu to update itself or will it just not update?

Are you asking to only update the "catch-all" update? This won't work. You need to upload all updates. If an update file fails to download then wyUpdate will just quit and say "Sorry, the update can't be found" (or something like that).

If you want smaller updates, then disable the catch-all update. (File -> Properties -> Updates & server files -> Uncheck "Create a catch all update [....]"
