Before you hunt for an ISO, consider that Microsoft provides a Docker image for legacy SQL Server testing.
docker pull mcr.microsoft.com/mssql/server:2012-latest
While this is not a traditional ISO, it gives you a headless Linux container running SQL Server 2012 for development purposes—no mounting required.
A Windows 11/10 Specific Note
If you try to install SQL Server 2012 on Windows 11, you will likely get a "This program has compatibility issues" warning. Ignore it. However, you must turn on .NET Framework 3.5 via "Windows Features" before running setup. Otherwise, the installation will fail silently.
