How can I sign a Gadget for Windows Sidebar?

Does anyone know how 开发者_开发百科to sign a gadget for Windows Sidebar (*.gadget)? I tried with signtool, but without any result.

Thanks

You need cabarc (from the Microsoft CAB SDK) and signtool (from the Windows 6 SDK). You can not sign ZIP gadget archives.

Follow the "Deploying" section at http://www.codeproject.com/kb/gadgets/gadgettips.aspx. I use the 'signtool signwizard' most of the time. You should already have an applicable code-signing certification (.cer) loaded into your certificate store.

Make sure you specify a time-server or your application will rejected from the Microsoft Gadget Gallery.
