Cant add theme to run on localhost using Wampserver

Hi Trying to add Enfold theme to Wampserver on my desktop computer without much luck.

Wampserver is latest version
Enfold is latest version
My machine is:
Windows 7 Ultimate SP1
AMD Atherlon 62 x2 dual core 3800+ 2.00 GHz
5 gig memory
64 bit

I am an enthusiastic amateur so be gentle :) Any help gratefully received

If I try to upload through the add themes at wp-admin/theme-install.php?upload i get this:

Are you sure you want to do this?

Please try again.

If I copy into the folder wp-content/themes when I go to themes in my wp dashboard I get this:
