According to an article in a recent Dick Eastman genealogy newsletter, RootsMagic version 4 now has a free “Essentials” version available for download from their website. This free “lite” version has many core features found in the retail version but it not as complete as what you pay for. Their website is http://www.rootsmagic.com/ if you want to give it a try.
Also, Legacy Family Tree software is available in a free version as well as a retail version. You can download the free version from their website at http://legacynews.typepad.com/legacy_news/. Their current free version is 7.0. They will require you to register with them for the “freebie” so they can send you notices of updates and other news.
These software titles are designed to run on any Windows platform. Both of these firms are very reputable and offer fine products. However, D-OGS does not endorse either of these firms. Use at your own risk. Remember, genealogy research is habit-forming.
