Support Package Installer has detected an inconsistency.

Dear Support, i am professor at a german university. I work on one PC with different Users. I Installed a EV3 Support Package under a student user with admin rights. Now I started Matlab R2014a under my user and there ist no Support Package >> matlabshared.supportpkg.getInstalled No support packages installed. To install support packages, enter supportPackageInstaller in the MATLAB Command Window. When I try to install the Package with +Add-Ons I get the error: Support Package Installer has detected an inconsistency.
The following support packages were found on the MATLAB path but they do not appear to be installed by you: - Simulink Support Package for LEGO MINDSTORMS EV3 Hardware
Possible causes: - You have recently cleared your MATLAB preferences, or - You are using a shared MATLAB installation and the above support packages were installed by another user.
Contact MathWorks Technical Support for guidance on restoring your system to a consistent state.
What can I do? Best regards Prof. Schneider

This inconsistency can be caused by any previous Support Package installation performed on the machine. Support packages can not currently be installed on multiple accounts. To avoid it, you can follow the steps below:
1. Delete the contents of the "SupportPackages" folder (not the folder itself) located inside the MATLAB folder.
Windows: C:\MATLAB\SupportPackages Mac\Linux: Documents\MATLAB\SupportPackages
2. Update the toolbox list to reflect the changes by executing the following command:
>> rehash toolboxcache
3. Reset the MATLAB search path to default by running the following commands:
>> restoredefaultpath >> savepath
4. Install the support packages.
Note that this solution will remove any partial or complete support package installations for other users as well. Currently, support packages are not designed to work with multi-user profile machines and as such, other users will not automatically see them.
As a workaround, you can copy the preferences folder of the user who originally installed the support sackage(s) and replicate it for other users. Replace the existing preferences folder for other users with the preferences folder of the original user. MATLAB stores its preferences under the user profile in:
Windows: C:\Users\<username>\AppData\Roaming\MathWorks\MATLAB\R2015a\ Max\Linux: ~/.matlab/R2015a/
The preferences folder is named the release name for the application. For instance, the preferences for R2014a would be in the specified location in a folder called R2014a.
This workaround would make it so that your instance of MATLAB will be able to see the Support Package that someone else installed on the computer.
Once a support package has been installed, you can use the follow command to verify that the installation was successful.
>> matlabshared.supportpkg.getInstalled
