CCS5 installation error on Ubuntu 10.04.3

Hello experts,
When I try to install CCS-5.0.1.00026-Sitara-ARM I get the following error message.
At first I set up Ubuntu 10.04.3, and after that I try to set up CCS5.
But the installation breaks because of this "Install DSP/BIOS 5" message:

Application Error

I need a solution. Please help me.
Thanks.
