h2. Install win32 version of python subpackages
4 1 Anchi Cheng
5 15 Anchi Cheng
Because all interaction with the scope uses COM interface that is only accessible through 32-bit architecture, python running Leginon component is the 32-bit version.  Use the 32-bit Windows files (those marked as win32 and certainly not the ones says 64) in http://emg.nysbc.org/projects/leginon/files for these.

*Talos has a 64-bit Python pre-installed unde default python location C:\Python27.  Therefore, we need to name our installation with another name, such as C:\Python27-win32.*
