    Windows 8 x64 does not like this software at all, in fact it blue screens it on a fairly regular basis. Besides, their software is not all that good and it causes more problems than it fixes. If you use it and you like it and it works well for you, then so be it, otherwise find something else as there are several much better than this....This is slow, laggy and useless in my estimation.

    This good tool runs only at WinNT or hiher, not on 9.x!
