I tried following this guide http://topazsystems.com/software/download/adobedcpluginhowto.pdf as closely as possible (I don't see the "Sandbox Protections"/"Enable Protected Mode at startup" section described in the additional step). When I go to the Fill & Sign tool, my only options for adding a signature to the PDF are Type, Draw, and Image. I do not see an option to connect to my signature pad. I'm using Windows 10. Any help is greatly appreciated.
