where is families
Should be a tree like this - obviously on your system it might be different and your country will be yours - see if the folder is there? there should be a libraries file with families in it - just search for libraries down the tree from Autodesk
don't try and search explorer as a term as there are thousands of libraries hits on a PC
Just go to your PC main drive (C:) - program data - Autodesk and try the RLT files
