Need Archived Installer for SSMA 10.3

Hi,

I’m running SQL Server 2022 Express on Windows 10 (64‑bit) and using SSMA for Access. With SSMA 10.4, I keep getting the error “Bad parameters for connection” when connecting via Windows Authentication.

I understand this is a known regression in 10.4. Could someone from Microsoft please provide a link to the archived SSMA 10.3 installer (Access to SQL Server edition), which works correctly?

Thanks in advance!

    Hi @Mario Jaile ,

    Microsoft no longer provides public download links for older SSMA versions. Only the latest build (10.4) is available on the official download page.

    To get SSMA 10.3 (Access → SQL Server edition), you will need to open a Microsoft Support ticket and request the archived installer. Microsoft can provide older SSMA builds only through support, not publicly.

    Link (latest only): Download Microsoft SQL Server Migration Assistant for Access from Official Microsoft Download Center

    If it won't works, then open a support https://support.serviceshub.microsoft.com/supportforbusiness/create case and ask specifically for SSMA 10.3 due to the known “Bad parameters for connection” regression in 10.4.

    Thanks,
    Akhil.
