Hello shep greene,
Thank you for reaching out to the Microsoft community.
Ensure your system meets the minimum requirements for SQL Server 2019. If any version of SQL Server is already installed, uninstall it completely from Control Panel > Programs and Features. Download the installation media for SQL Server 2019 from the Microsoft website. The media is usually in the form of an ISO file.
However, there is a dedicated support community for SQL Server issues. I recommend reaching out to SQL Server community. Please reach out to SQL Server community by visiting this website SQL Server - Microsoft Q&A; I am sure that our experts from that team can address your query effectively and accurately.
I apologize for redirecting you to a different community, but I believe this step will ensure faster and more accurate assistance for your specific scenario.
Thank you for your cooperation and understanding. Please do not hesitate to post your queries in Microsoft Community and we will always do our best to assist you!
Appreciate your patience and understanding. Have a great day!
