While a download order of a new BibleWorks 10 license immediately provides a BibleWorks 10 activation code, those wishing to upgrade from a previous BibleWorks version cannot make use of the download until their code is transmitted to them following the purchase of an upgrade license and the validation of their previous version's activation code or serial number.BibleWorks versions 3 through 9 were distributed on optical drive media (CDs or DVDs). In either case, no CD or DVD drive is required for BibleWorks installation: instructions for accomplishing the installation appear here. BibleWorks 10 is distributed either by download or in a media version on a flash (thumb, USB) drive.
