The first time I attempted the install I had selected “Client Tools Connectivity”, “Client Tools SDK”, and “SQL Client Connectivity SDK”. I couldn’t reduce the components / features that I was installing because I was only installing the “Database Engine Services”. But using the default accounts didn’t help. And I had found a few posts / articles mentioning possible install issues due to permissions. I was using the “SQL Server” account that I was already using for SQL Server 2017 Developer Edition, so I figured it would work and so was not using the default service accounts. With no other information to go on, I thought that maybe it was a permissions issue with the account I specified as the service account for the “Database Engine” and “SQL Server Agent” services. I don’t know if this was a factor in the install failing (seems unlikely), but it was something that I had not done when uninstalling previous CTPs.įirst: reduce custom install configuration But, I was allowed to uninstall “T-SQL Language Service”. I couldn’t remove “SQL Browser” or “VSS Writer” due to dependencies: SQL Server 2017 was still using them. Had I done anything differently this time? The only thing I can think of is that, after uninstalling the SQL Server 2019 CTP 2.4 instance, I checked the list of installed apps and noticed that “SQL Browser”, “VSS Writer”, and “T-SQL Language Service” were still installed. TL DR You can skip to the solution, if you don’t want the details (but seriously, who doesn’t want all of the exciting details?) But no, there was none, not even a small piece of unhelpful information. That might have been ok had there actually been any information that followed. Use the following information to resolve the error, and then try the setup process again. Each time it would get through the first several steps of the installation process, but then encounter some condition causing it to rollback and finally end with the super helpful error message of:Īn error occurred for a dependency of the feature causing the setup process for the feature to fail. The other day, I was blessed / honored / delighted to waste several hours attempting to install SQL Server 2019 CTP 2.5 over and over again.

(last updated: 00:30 EST / 05:30 UTC ) I had gone through the process of uninstalling the now obsolete SQL Server 2019 CTP, and then installing the new CTP, for the four previous updates and did not encounter any problems.
