How to set the default version of Matlab between two versions?

I once installed an older version of Matlab2012b before and have used for a time.Now I managed to install a 2014a version but it seemed that the 2014a version was set as the default version after the installation.I want to set the 2012b version as the default one because it interacts with other softwares better for me,since the interactions happen only between the default ones.Is there any way to change the setting?
