REVIT 2010 - revit rendering library not installed - assetlibrary_base.fbx

For some strange reason my RAC 2010 software started giving the the following warning when I started up my REVIT.

"revit rendering library not installed"

After some minor investigation I noticed that REVIT was looking for the librabry file named "assetlibrary_base.fbx' file in the wrong place.

So under the REVIT 'Options' > 'Rendering' tab "Render Appearance Library Location'

I reset the path from:

'C:\Program Files\Autodesk Revit Architecture 2010\Program\"

TO

"C:\Program Files\Autodesk Revit Architecture 2010\Data\Rendering\assetlibrary_base.fbx'"

AND PROBLEM SOLVED !

YEAH !
