well i have found its solution.....i thought to share it with u all...
even in free public version.....u can apply even non vista icon packs.....for win vista


ok do as i tell u stepwise....
1. load an icon set in icon packages tab
2. apply it..
3. non vista icon packs wil apply rest but wil not apply to live folders..
4. go to icons n cursors tab
5. click on folders
6. u wil see live folder front n back on default icon choice...
7. right click on it..n click Change icon
8. a new window will popup..select ur icon set from left panel
9. give it the folder icon u want..
10. aplply changes...(tab at right top)
now this icon package will work fine...even on rebooting too

but u have to do it everytime u apply new package
but in my win vista i noted sumthing....i did this step once..now when i apply non vista icon package...it applies with live folders
enjoy!!!
