One thing I have learned over the years is to never bother with these free downloads from companies or organizations unless they are a well supported open source project. What usually happens is after 5 or so years you can't find that program anymore for download and you find out it won't work on someone else's system because the manufacturer never tested with with all versions of windows. Keep your documents in the most basic of formats, plain text, csv, etc. Don't even trust programs such as Microsoft Office even though they see to be very popular as they have dropped support for some of their older file versions in the past.
