title: Error when trying to run python 3 (python.exe is not a valid win32 application)
body: <p>I have python 3.3 on my Desktop and works perfectly fine. I'm trying to install 3.5 on my main laptop I work from, but once it is "successfully installed" (the message the installer always gives me) It doesn't want to open. I get a message saying python.exe is not a valid win32 application. My OS is windows vista.
