Leginon

h1. FEI Talos/Arctica installation specifics

h2. Install win32 version of python subpackages

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.

Here is the full list

{{include(Windows_32_External_Package_Installers_Common)}}

{{include(Comtypes_installer)}}

h2. Important: Install Python under a custom named folder

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

This is set during python installation.

The rest of the installation is similar to other FEI systems.
