Hi, there are several ways to do that besides starting python scripts with a double-click on a desktop icon (that can only work with the one and only python version of the registry).
One is to start the new python version directly from a "DosBox". You could copy python.exe or pythonw.exe from the new version directly into the directory, where your python script is - both are only some kB large - and then execute "python your_script" in the cmd.exe. After some "cd"s to the directory of your script. Besides - it is no bad idea to have some copies of the cmd.exe at several places of your file system - the correct run of cmd.exe is not depending on its place in C:\Windows\system32. It also runs from external disks. This is, how i do that, not optimal probably, but easy to understand. Joost -- http://mail.python.org/mailman/listinfo/python-list
