How to edit registry on pocketpc to change how IE displays python files.

Ive installed pythonce and Tkinter on a pocketpc 2003 2nd edition. And it runs 
any python scripts on it. I want to be able to connect to a python file on a 
share and have it run the python file but in Internet explorer it just opens 
the python file as a text file. So i downloaded a registry editor on the 
pocketpc to try and change the way IE opens the file. Either to open it up in 
a save as dialog box and the run the python file like it would do for say an 
mp3 file or to run the python file directly in IE somehow. However im not 
sure what needs to be changed in the registry. In the python file I tried 
adding a BroswerFlag to the .py under file associations but that didnt seem 
to work. Any help would be appreciated on whether this can be done.
