CleanDisk3 - Norton Utilities don't function.

Recently installed CleanDisk3 and the 6 Windows Utilities work fine, but the 6 Norton Utilities don't. Clicking on each of them (DiskDr; WinDr; SpeedDisk; UneraseWiz; ConnectionDr; RegistryTracher) gives a "Specified File not found XXXX.exe" message box. There is no help file for me to read. Does anyone know what may be causing this and the fix? (I suspect I have to pay for the full features - if so, is it worth the money?)
thanks - and sorry if this is one of those (many) dumb questions I sometimes post.

CleanDisk3???

Clean Disk 3 aka cdisk3 - that's what it says in properties. Hasn't anyone heard of this before, or just not this version?
