SQL Server 2019 Upgrade - Problem
I have a problem server it appears. It had MSSQL 2016 Dev and I was able to upgrade it 2017 Dev. However in the process of going to 2019 Dev, I got an error;

There were several attempts to install as a result of other problems. I cannot find anything specific to this error on the web. Does anyone have an idea of where I need to look or a solution? BTW I did a new install on the same server and although SQL Server is running, the R and Machine Language failed to install.
Thanks

Start a new, own thread and describe your issues detailed.

- sreemaceCopper ContributorOk Olaf, will do. But I went in depth a bit more and I doubt windows firewall is disabled on win 2019 and it fails @ below step. I will try enabling windows firewall and see how it goes.
