All,
         let me break down the 2.1.7 upgrade process for you a bit further.  As there are added frustrations since this is a 'new' file for most browsers/AntiVirus/Windows stuff...


From the 2.1.6 HELP ->  Check for Update

Say YES to everything.

As that starts downloading ->  Turn off your AntiVirus for the next 30 minutes (it is slowwww)

Windows will moan about the download.

Click - > more details

Say Yes

2.1.7 is now loaded ...

Let it start and load whatever it does that takes longer than booting Windows 8 on a 286 PC

Reload the Block Chain - > have dinner, in fact have dinner and drinks - this is slow....

Rescan your wallet  - >  take a post dinner nap

Wait for it all to start again

Pray

Rinse and repeat as required until you have a functional wallet that holds some promise that the POW rewards don't go [?]....


Seriously though - well done Devs, let's hope you have the solution with 2.1.7 as 2.1.6 was driving me even more insane than I am normally
