Couchbase Server 6.0.2 and 6.0.3 install error

I am attempting to install Couchbase Server and have tried with 6.0.2 and 6.0.3 on my development Windows 10 machine. When I complete the install, I attempt to browse to http://localhost:8091 and it says “Site can’t be reached”. I have attempted every suggestion that I could find on the forums. I have run the the cbcollection_info.exe and have the zip file but an not allowed to upload as a new user.
Can someone please allow the upload and help me figure out why I can’t get this up and running?
