Microsoft SQL Server Express: this version of the installer is no longer supported

Question

I'm trying to install Microsoft SQL Server 2019 Express but I keep running into the above error message.

I was originally running into a separate error message when trying to install that said

A required file could not be downloaded

I followed the instructions on the following thread, which solved the original issue, but now I have a new error: A required file could not be downloaded while installing SQL Server 2019 Developer

There doesn't seem to be much info about this online, only thread I've found is brand new and I'll be monitoring it for a solution: https://docs.microsoft.com/en-us/answers/questions/816770/sql-express-2019-the-version-of-the-installer-is-n.html

I have already tried restarting my computer.

Thanks to anyone who can help.

Answer 1

I tried again today with a new download and it worked! They must have fixed the issue. Hopefully everyone else can get it running today.

Answer 2

I had the same issue, I executed the Powershell script as mentioned in the other thread (run powershell as an administrator), restarted my PC and used the re-downloaded installer (from the url in the error message). This time the installer went through. Hope it helps!
