First download the lastest version of the codename-alex-redist package from the sourceforget files page: http://sourceforge.net/project/showfiles.php?group_id=70961.

Unzip the archive to a temporary location and copy all the files in the src subdirectory to a location on your computer. Due to the way EasyUO passes the call command it is best to choose a directory path that does not have dictory names longer than 8 characters. I.e. C:\EasyUO\Lexia\
