You can now download the SQL Server 2016 Release Candidate 3 from TechNet Evaluation Center. In the below screenshot, I have chosen to download it as ISO copy. This will enable me to attach it as disk drive in my Hyper-V Virtual Machine.
Based on few browser plugin issues and local settings, the download may not start immediately. Hence you can click on Manual download again in case if the above chosen ISO file does not download.
I am looking to find if all the previous issues that I faced with previous releases have been fixed in this new Release Candidate 3 or not.
Have a good journey in this SQL Server 2016 as we have now come to the last RC3 before we get the full SQL Server 2016.
