I am trying to sign an XLA file of our with our code signing certificate. I am following the instructions here but they require that Excel know of the signing certificate.
Is this a workable way to do this? And if so, what else do I need to do?
Or is there a way to do it with signtool (it tells me it's an invalid file format)?
Or some other way?
this (never says how to do it) & this (asks how to do so in code - and the reply is you can't) don't answer this.
