We have a server running SQL Express 2019 build 15.0.2120. I am not able to install CU 28 or CU 1 for that matter. The remote registry service is running, I am running the installer with full admin rights, disk has ample space etc... The installer states their are no SQL instances or shared SQL files present etc..I have confirmed twice that I am using the correct download for SQL 2019

    I think the issue is that you have a couple of GDRs installed, and then you are the GDR train. You need to uninstall these to get back to pure RTM and then apply the CUs.

    Hi @rr-4098

    If you are using SQL Server with GDR, you may need to install SQL Server 2019 GDR builds.

    See below:
