Hi ,
Got some info back from the Data Team regarding your Query
Currently the supported version of Foxit Reader is the MSI / Enterprise version. This edition is always a little behind in version numbers.
At the moment, the latest version of this edition is 5.4.5.0114, released on 19/Jan/2013.
The Data Team are in the process of testing and integrating this version of Foxit into our XML ,and should be available this week. Probably the Thursdays XML release at this stage
Hope this information helps ,
Let me know if you have any queries.
Anthony
