This happens when the update UI detects a feature that defined an 
install handler.  An install handler is code that the feature needs to 
run during the install.

The new provisioning infrastructure (p2) does not yet support these 
install handlers, so it has to start the Update Manager from 3.3 in 
order to run them.

This should get fixed in 3.5 - there will be some kind of migration path 
so that features with install handlers can be installed the same way as 
others.
