OK - I found the SOLUTION.
At the bottom of the long list of updates that were pending install,
there was a button labeled "NEXT"
I clicked on that , and lo and behold, up popped a window to Accept the Software license(s)
Once I did that, I was able to then click the "install now" button and all the pending installs were then compl;eted.
Simple.......glad I stumbled upon the solution !
