I am using Armory 0.96.0 with bitcoin core 0.14.2.  I have been advised to update to the latest version of Armory which I assume is 0.96.3.

I have 2 questions:

1.  Can I just install Armory 0.96.3 straight  over 0.96.0 (I'm using windows x64 installer) or do I need to totally remove 0.960 and do a clean install of 0.96.3?

2.  Do I need to update bitcoin core or can I stay with my existing version 0.14.2
