Hello all,

I wanted to follow up and let you know in case it helps someone else in future; I resolved this issue I posted about Saturday 11/24/18 (original post below). I'm running Windows 10 version 1803 (build 17134.407). After trying all the responses received here as much or well as I could and ruling out interference from my antivirus protection, I selected 'Reset This PC/Get Started' and then selected 'Keep My Files' (screenshots attached). After that I was able to download and install PostgreSQL 11, launch pgAdmin 4, and successfully log in to run PostgreSQL. I am grateful for all the responses from support community members!

Thank you. ~ Anne Marie
