Seems that is the norm for anything like this ... the core program (original release) has to install then all the updates that have occurred along the way.
Had to do all these when I had to completely restore my Win 7 OS. The original release was from 2010. Fortunately it was all covered under my Dell warranty.
Seemed like the updates took like forever to get done.
The same with Vista, on several occasions I have had to resort to a full DELL restore to fix problems that I could not fix myself, this restores the PC to the condition it was in when purchased, I just leave it switched on until all updates are current about a day then have to reload all my programs another day at least but it sure fixes things, of course you have to make sure you have done a back up of the important stuff.
