External Email - Use Caution
The wiki information may be out of date. Having multiple versions of freesurfer installed on your system may cause running an application bundle like freeview.app to crash if the system is confused about which version of freesurfer is installed. So I would avoid having multiple releases of freesurfer on your system.
If you expanded the tar archive instead of doing an actual installation with the .pkg installer, then I would drag your ./freesurfer subdir(s) to the trash, empty the trash, and then check no freesurfer distributions remain on your system. Then try installing the version of freesurfer you need by downloading its .pkg file, double clicking on it, and following the menus.
The installer .pkg puts an uninstall script as, /Applications/freesurfer/<release number>/uninstall.sh - into each freesurfer release. Running that uninstaller is the most reliable way to tell the system that freesurfer distribution (and Freeview.app) have been uninstalled.
There's no need to add a license file to each freesurfer distribution. You can keep your license file in one place, e.g., your home directory where you login to. Then in your environment set FS_LICENSE to the path of your license.txt file. If it's in your home directory, then you would do $ export FS_LICENSE=$HOME/license.txt
If you add the setting for FS_LICENSE to your shell initialization file, then it will be defined every time you open a terminal window. Your license file will be found in that central location no matter what freesurfer release is installed.

I renamed my old "freesurfer" folder as instructed on the wiki. However now freeview crashes. it opens but when i try to load volume it crashes. Below you will find the report. (this happens if I use either the old freeview or new freeview).i also got a new license and put it in freesurfer directory. I also moved to trash then deleted the old fs but still get the error.
