With Drive PX2, how to reinstall DriveWorks in latest version?

I have some problem with using DriveWorks-0.3. So I want to reinstall driveworks in the latest version in my DRIVE PX2 (OS seems to be Ubuntu 16.04 LTS). But I cannot find the way how I can reinstall in the latest version?

I’m looking for your help, thanks.
