Error-Signing MSIX package using SignTool RRS feed

  • Question

  • Hi

    Starting in version 1806, Configuration Manager supports  converting  existing Windows Installer (.msi) applications to the MSIX format.

    I tried creating msix package via SCCM, but I am facing issue in signing the msix package from sign tool SDK

    ( I am using Windows 10 SDK (10.0.18362.0) for Windows 10,version 1903)

    Error :
    SignTool Error: This file format cannot be signed because it is not recognized.
    Can u help me out in this issue?

    Also Is there any way to sign the msix package from SCCM itself?


    Thanks in advance

  • This really has nothing to do with ConfigMgr but I'll see if I can get someone to help.

  • Can you look in the event viewer under Applications and Services Logs > Microsoft > Windows > AppxPackagingOM > Microsoft-Windows-AppxPackaging/Operational and share that information?  

    Is it possible to send me the package as well to look at?

  • Hi Jason,

    Please let me know if u had a chance to look in to the issue or get any help from the community.

    We tried signing .EXE and .MSI using Signtool.exe and  could manage to sign  the package successfully.Only signing .MSIX package is throwing errors

    This arises doubt whether Signtool is the supported method to sign .MSIX packages ? Please confirm

    Any help in this regard is much appreciated.

    Thank You !!

  • I didn't need help from the community, I asked John V, one of the main program managers at Microsoft for MSIX to help and that's why he posted here and is requesting further information from you.

    Looking at the screenshot you are using an older SDK.  The documentation link you reference mentions "starting in Windows 10 Insider Preview Build 18945, you can use SignTool in the Windows SDK to sign your MSIX apps with Device Guard signing."  Please try an updated SDK.
