How do I obtain PDF Xchange drivers for my version 5.2 PAF companion? I was using this program for about 10 years and then stopped because I went to work full time and now that I am retired and want to get back into genealogy - my program will not print out forms and tells me I need PDF Xchange drivers. Everything else seems to be OK and I have not lost anything - I have Windows 7. Can I update to 5.4 or greater and still be OK?
