Hey guys,
maybe you can tell me which .exe file is the Authenticode Action using and by chance could you tell me which command line parameters are used?
We are currently experiencing issues with signing from our team build and now i just need some clarification.

Hi Nachtmahr,
The Authenticode action uses the CAPICOM interface to perform the signing. The action creates a CAPICOM.Signer and loads the PFXFile specified into it. Next a CAPICOM.SignedCode object is created and the Filename, Description and URL are assigned to it. Lastly the SignCode object is signed by the Signer.
You can find the CAPICOM reference here:

We also should be clear that the Authenticode actions are deprecated as the CAPICOM interface is deprecated / no longer in later versions of Windows. We suggest using the sign tool action now.

Okay, thanks for clarification.
