SQL Server 2019 Installation Failure

Viewed 1612

I'm getting this message when installing SQL Server 2019 Express.

The supplied user buffer is not valid for the requested operation.

sql error

Retrying just pops the message again, canceling fails the Database Engine Services and the Full-Text sub-feature.

failed install

I've tried uninstalling and reinstalling the instance, restarting my machine, etc. I have a brand new Surface Book 3 15" i7, 32GB RAM, 512GB SSD with plenty of storage.

Update

  • The setup is running as administrator
  • I've tried disabling Anti Virus

This is not a great solution, but installing SQL Server 2017 instead of 2019 fixed it for me.
