h1. FEI Talos/Arctica/Glacios 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.
