I had installed AutoCad 2013 x64 at Win XP (Eng).
No ribbon in application.
Command "RIBBON" says "Unknown command".
But command RIBBONSTATE says 0 (read only).
I tried: install ALL service pack for 2013, install ribbon hot fix (http://images.autodesk.com/adsk/files/Readme_AEC_A
I tried call ribbon from command line, from menu Tools -> Palettes -> Ribbon.
I dons't work. NO RIBBON!
In 2013 x32 (Win XP) no problem - I have ribbon and no problem.
Can you help?
>> Command "RIBBON" says "Unknown command".
When you have entered _.RIBBON (including "_" and ".") and AutoCAD tells you that this is an unknown command then it's installation is defect. Try a repair-install or (clean) uninstall and new install to get it running (using admin-rights and switched off all defending-/protecting software).
Good luck, - alfred -
