MSIX Packaging Too: SignTool Error: certificate file not found

I tried to convert msi to misx by using MSIX Packaging Tool, but faced SignTool error.   Before converting, I made the temporary certificate by following steps. <https://docs.microsoft.com/en-us/d...

    You can run signtool.exe manually to sign the package.  

     

    https://docs.microsoft.com/en-us/windows/uwp/packaging/sign-app-package-using-signtool

     

    Usually something like this: signtool.exe sign -f mycert.pfx -p {password} -fd SHA256 -v appPackage.msix

     

    The command line would tell you a specific error to help troubleshoot.  You can also look in the event viewer under: Applications and Services Logs > Microsoft > Windows > AppxPackagingOM > Microsoft-Windows-AppxPackaging/Operational

     

    It has errors specific to packaging.  If you file a feedback hub item on the issue that would help us out as well.

John,

Thank you for your prompt reply.

Thanks to your advice, I was able to sign my package manually, but still not be able to install it.

The error massage I got is below.

 

"App installation failed with error massage: error 0x800B0110: Opening the package from location <my package>.msi failed. (ox800b0110)"

 

I suppose the packaging didn't finish because of sightool error although I misunderstood it finished successfully.

Attached files are feedback hub logs when MSIX packaging error occurred (which I referred in the previous post).

I hope it will help to solve this problem.

 

Thank you.

    Hi K_N11no,

     

    That error implies that you are using an invalid certificate for package signing. I suspect the instructions you followed for a WCF certificate resulted in a certificate not quite right for application packaging.

     

    Please check out:

    https://docs.microsoft.com/en-us/windows/uwp/packaging/create-certificate-package-signing

     

    If you still encounter problems with the certificate generated via those instructions, please let me know.

     

    Thanks!

    James
