I want to use own tool chain, how could i install new too chain in the DS-5?

I have the same problem, but slightly deeper:

When trying to select toolchain (Pref/DS-5/Toolchains) on blank tab page you can see: "An error has occurred when creating this preference page".

and textbox with caption problem occured and text inside:

unable to create the selected preference page.

an error occurred while automatically activating

bundle com.arm.eclipse.build.toolchains (457).

error log/exception stack trace:

I tried to clean installation and reinstall (DS-5) only and (EDS+DS5) several times, but it doesnt help. So I failed to change TC and do build manually.

Maybe someone have and solved the same problem ?

PS: im using DS-5 installed with EDS 16.1.0.916 by Intel/Altera (Version: Luna SR2 (4.4.2) Build id: M20150204-1700)

I also had this problem when using DS-5 on Ubuntu 16.04. I had to run DS-5 as root for toolchains to work properly.
