If you do not have MATLAB Coder installed (as indicated by ver) then the commands ccoder and coder will not work and should not be installed. That ccoder is recognized at all is probably a bug. However, the directory toolbox/coder may be installed and contains shared components used by other products.

I apologize if I didn't understand this properly but think the command is just 'coder' and not 'ccoder'. Upon typing coder in the command window, a GUI will pop upfor the new project file and then you continue as you normally would.

Hi Anjinkya,
I faced similar problems for getting Matlab coder to work.
Can you try the following commands:
$ rehash toolboxcache
$ restore defaultpath
$ savepath pathdef.m
And see if matlab coder works for you.
