Warning Name is nonexistent or not a directory

Hi, I have two different versions of Matlab in my PC, Matlab2010a and Matlab2015b. So when I run one One of them for example Matlab2010a I get In the command windows the following warning :

Warning: Name is nonexistent or not a directory: C:\Program Files\MATLAB\R2015b\toolbox\shared\dastudio\depviewer
Warning: Name is nonexistent or not a directory: C:\Program Files\MATLAB\R2015b\toolbox\rtw\targets\shared

I fixe the problem by :

restoredefaultpath;

matlabrc

savepath

Now when I run Matlab2015b I get In the same warning, when I fix it as before, if I switch to use Matlab2010a the same warring show up again.

How can I fix the problem?
