AutoCAD 2010/2011/2012 DWG Format

Trouble with embedded OLE DWG objects in word 2010 not opening with AutoCAD 2012 

We have a user that can't open some OLE DWG files from within a word document. He had 2010 AutoCAD LT on his machine for a while then was upgraded to 2012 AutoCAD (non LT) once that was there LT 2010 was unistalled. since then he has not been able to open certain embedded OLE files within Word. Other users that have other ever had AutoCAD 2012 have no issue opening this embedded DWG files. 

i found this thread (http://forums.autodesk.com/t5/AutoCAD-2013/Editing-Excel-2007-Embedded-Autocad-Drawing-Problem/td-p/...) which sounds exactly what is going on with my enduser. But the fix provided is for AutoCad 2000-2012 not the LT versions.

Can anyone help as he is really struggling with this issue.

from the looks of that link, there's no reason his fix would not apply to LT as well as full

No I expected it not too but it was worth a shot. Need to know what the reg key is the pointer for LT
