Hello Vikas,
When you install a support package, MATLAB tries to add the necessary directories to your path. However, if your 'pathdef.m'(path definition file) is read-only, it may have failed to save the updated path. This means the path changes are only active until you restart MATLAB.
You should have seen some error or warning text when you installed the support package, indicating that the installer failed to save the updated path. You can save your path to a location by using the "savepath" function with an input argument that specifies the full path. To ensure MATLAB uses this path in future sessions, save the path to 'pathdef.m' in your MATLAB startup folder.
Additionally, please refer to the following MATLAB Answers thread which might resolve your query:

Hope this helps.
