Pronterface install problem

[old man emu]

I recently re-installed Window XP with Service Pack 3 on the computer that I do my printing with.

I downloaded Printrun-Win-Slic3r-12July2013.zip , unzipped it into a folder in C:/Programs and tried to run it. It comes up with an error message saying that it did not install correctly. (Slic3r was in the same download, and it runs correctly.)

The install instructions say to locate the pronterface.py file and make a shortcut to the desktop to make pronterface run. I can't find that py file anywhere.

I have also tried to install the March 2014 updated version, but have the same problem.

Any ideas about what is going wrong?
