A 64-bit version should be available if one pays $29.95. Some similar free software has this feature. I think it is good software because I've used the free edition. Not having a 64-bit version for the free edition is understandable, but if I pay money for something I'd like to have the option to have a 64-bit version. If one really wanted a 64-bit version and was willing to pay for your software, but turned away because of no 64-bit version is a terrible loss in my opinion. Anyway really nice software. I also have your other software, Kryptel Standard which is excellent, but no 64-bit version for that one, too.
