does anybody know what's causing this?

when installing, i'm meant to un-check the read-only box (set permissions to 777) in the properties menu of the catalog/image folder. I have tried doing that countless times but each time i go back to the properties window there goes a box-checked for read-only.

has anybody encountered this before? how do i get windows to un-check the read-only box?

i'm currently doing an offline installation using easyphp.

can anybody help?

thanks!!
