Installation of ppower4 with Windows XP

Recently I learned how to use pdfscreen for computer  presentation.
The document for it suggests to use ppower4 for the post processing.

I have been using latex for a long time. Preparing .pdf file for pdfscreen 
creates no problem for me.



It seems that \pause is a very useful command.
In general, the demo from the ppower4 page looks fantastic...

I have difficulties installing  ppower4.

I use Windows XP system.  I dounloaded

and keep them in the same directory as my pdfscreen files are.
But probably it is wrong...  Where do I put all these files?

Path?

Do I need to downloaded vlatex?

I am afraid that I already asked too many question...
