Ugrade from 17.0 to 17.1

Category: Software
Product Number: LTspice
Software Version: 17.1

I did not find LTspice 17.1 installation instructions, are they located anywhere? I want to upgrade from 17.0, for which the installation directory is C:\Program Files\LTC\, but the 17.1 default target is C:\Program Files\ADI\LTspice\
Do I first uninstall 17.0?  Do I select the 17.1 installtion direcory to be the same as alreday exists for 17.0?  Will any of my custom lib parts or other settings be lost?
