    How to Re-Sign an Old CS5.5 Extension


      We have a large customer for whom we wrote a CS5.5 InDesign Extension about 5 years ago. 2 years ago we re-built and signed the Extension. The code signing cert was only good for 2 years. 2 years have passed and we no longer have the old Extension Builder available or anyone who would  know what to do with it ...


      I thought I could take the old ZXP file, unzip it, remove the META-INF dir (and the signature.xml file in it), and then resign it with ZXPSignCmd and a new cert.


      I thought wrong.


      The Adobe Extension Manager reports that the signature is not valid.


      I would appreciate any help.
