Thanks for the info, but I followed the instruction provided. When I "Click here to sign this section" I got the popup that says "The form contains changes... Click Ok to update the form, and try signing again." I clicked Ok and I'm prompted to install $(loc.IPFS DSIGRES CABNAME) and dsigctrl.cab. I completed the installs and the next message I get is "An error has occured. Please try again." At this point every time I attempt to sign the form I get the error occured message.
Any other suggestions I can try?
