As for the "Free Dow..." part of your request, I must note that Hex-Rays IDA Pro 7.0 is a commercial product, and as such, it is not available for free download. However, interested users can download a free trial version from the Hex-Rays website to test out the decompilation features. Additionally, some versions of IDA Pro, such as IDA Pro Free, offer limited decompilation capabilities at no cost.
