Here is a solution to the Hexalock problem for those that have not made 2 posts and therefore do not qaulify to download GoldStar611’s code. With thanks to GoldStar611 for pointing me in the right direction.
Install a copy of Foxit and rename the Foxit reader executable to AcroRd32.exe.
Install a copy of PDF creator and set it as your default printer.
Load your Hexalocked CD and run Start_Here.exe (or whatever launches your particular CD).
Now launch Foxit and use it to open the PDF files on your CD.
Print your PDFs to PDF creator and save them in a safe place.
This is not a perfect solution as you lose all of the indexing that is in the original files, but at least you now have a PDF file that you can copy, archive and print.
This seems to work because Foxit does not enforce the no print security that is in the original PDFs and which Acrobat does enforce.
