Note: THIS IS NOT THE SELLER'S FAULT and this is not a comment about the seller or the product content. I bought Version 4 because it said it can be used on Windows 98. My Windows 7 PC says it will read Windows 98. However, I can't get it to work. I have looked at numerous websites and there seems to be a point where software gets so old it can't be read on newer systems even if the systems say they can. I bought this as an experiment because my computer is about 3 years old and I thought it might work but I was ready for this result. If you have an (even) older computer this might be an option for you, but newer computer? You are taking a risk.
