This is typically caused in a disconnected environment where the trusted certificate authorities are not updated automatically.
Also, when using the new timestamping Cross-Root certificates, the /ac parameter must be used. Read more about in the Authenticode Signature Verification Fails with New Timestamping Cross-Root article.
The following command line will address this case:
Code: Select all
sign /ac "PathToCert\CodeSigningCrossCert.crt" /tr http://timestamp.digicert.com /td sha256 /fd sha256 /a /d "[|Manufacturer]" To use the above command line, select the Custom option for the SignTool in the Digital Signature page and configure it as below:

Hope this helps!
