MATLAB: Do I receive an error while opening SimMechanics 2.6 (R2007a)

mblibv1.mdlphysmodsimmechanicsSimscapessc_checklicense

I have SimMechanics installed on my machine but I do not see it in the usual Simulink library browser. Also, when I try to open SimMechanics via 'start -> simulink -> simmechanics -> open block library', I receive an error message 'The specified module could not be found' along with the following error:
 Warning: mblibv1.mdl, line 6: Error evaluating 'PreLoadFcn' callback of block_diagram 'mblibv1'. Undefined function or method 'ssc_checklicense' for input arguments of type 'logical'.
 > In C:\Program Files\MATLAB\R2007a\toolbox\physmod\mech\mech\mechlib.p>mechlib at 35
 Warning: mblibv1.mdl, line 459: Unable to load 'mechanical' due to the following error
 'The specified module could not be found.

Best Answer

This error occurs due to unavailability of Simscape in the installed version of MATLAB 7.4 (R2007a). Note that Simscape is a required feature for running SimMechanics 2.6 (R2007a).
Hence, to resolve this issue, uninstall MATLAB 7.4 (R2007a) on your machine and then re-install it along with Simscape.
