Adding a save as option to AutoCAD Mechanical for autodesk lt 2008

[Anonymous]

I am using AutoCAD Mechanical 2013 and need to save a file as an AutoCAD LT 2008 for a friend to work in. I can only save it as AutoCAD LT 2004, is there a way for me to add AutoCAD LT 2008 as an option? If not is there a compatibility pack for him that he can download. There was a slight issue in the transfer. Im not doing anything that uses the mechanical features, just normal autocad features. The option for my computer is better if it is possible.

2008 DWG is not a valid format; try 2007 DWG format.  Both of you can also use DWG TrueView to down-convert DWG files to earlier versions.
