Free trial works perfectly. Win7-64 gave me no trouble with it. I can only assume people that had trouble with it are not full admins on their machines... perhaps in a corporate lock-down environment? Anyway, not a single problem for me.
None so far.
Does exactly what is says it does, and does it well. It's fast, too. I will be buying a full license for this.
