    This error code could be just a sign of bad exe-using Win32 signtool on x64 binary or when you are trying to re-sign an already signed binary file.

    Please check if you have these problems with your app.

    Besides, this forum is about desktop application compatibility issues. Your case seems more related to .Net sign tool, this forum isn't suitable for your case.

    Best Regards,

    Baron Bi
