I highly doubt that you're going to be able to run the ancient quicken program on any newer operating system.  You can try to back everything up and restore it to a new version but skipping many multiple releases may cause problems as well.  Since the end of year is approaching I'd get a new computer and a new copy of quicken (FYI, I think they've gone to annual licensing) and start fresh with the new year.  And if you're lucky you'll be able to restore your old data as well.
