Possibly a limitation of the installer package.

Typical open source licences aren't written to cover future updates, so 
there is a new licence being given.  This step may not be strictly 
necessary for bare licences, but given the populare confusion between 
freeware, open source and "public domain", possibly desirable.

Commercial software updaters often require agreement to a supplementary 
licence agreement, at this point.

Needed.  A user might change the selection, or there may be new choices.

Redundant, but only if the installer is able to find the old folder.

> 5.) Confirming the completion

Desirable.  This represents the start of the commit for the udpate, and 
it needs to be clear to the user when they are going to do the permanent 
change.  I sometimes dry run installs.

Possibly built into the installer package.
