Theme - How to Apply Custom Themes

No one knows the solution?

he must miss a program can be? required to operate the file?
Being a theme for windows 7, it does not come from my OS

So for the installed theme (all same theme) is working properly except for background records that do not appear.

I found a program like Windows 7 Folder Background Changer that can launch his own images (this starts correctly, but images still do not appear ...)

Then all I have to even find a small program to add a folder tab background change in the system to counter made windows 7 that I do not know why not to let me be me or my pictures lol!

And the magic I was able to bring up! (see picture)



However, all this is a long process that has not solved the initial problem of background that should appear with the theme ...

Moreover, all this is not explained in the tutorial.
The history of backgrounds and all.

In expectation of help
