Installing and Using Themes and Icons in LL

[Wirezfree]

Hi Looking for some help.
I installed some themes referenced by Kirkx from noobslab.
The installs did not produce any errors.
I could select the themes O.K, but on the icon tab there is a ! next to the Win7 icon item
It gives a message(warning):
"This icon theme as no cache file, you can create this by running"

Code:

gtk-update-icon-cache /usr/share/icons/Win7-icons/

by itself it failed
So googling gave me the fact you needed to add "index.theme"

Code:

gtk-update-icon-cache /usr/share/icons/Win7-icons/ index.theme

Tried the command without & with sudo:

Code:

dave@hp-laptop:~$ gtk-update-icon-cache /usr/share/icons/Win7-icons/ index.theme
gtk-update-icon-cache: Failed to open file /usr/share/icons/Win7-icons/.icon-theme.cache : File exists
dave@hp-laptop:~$

Any guidance welcome...
Thanks... Dave

Any ideas or suggestions how to fix this..??

Thanks... Dave
