I totally disagree with you. Many use Windows 7, Vista and XP x64 bit and there are advantages to using 64 bit or they would not have made it. If Piriform does not wish to make a X64 bit version of this software, all they need do is say so, simple as that., Those of us who desire X64 bit software, can move on to other software. But to deny us x64 bit because you personally do not see any benefit, is ridiculous and nonsense.
