Hello,
I've managed to successfully install Code Composer Studio 6.2.0 inside a Ubuntu 16.04 64-bit VM (with the help of http://processors.wiki.ti.com/index.php/Linux_Host_Support_CCSv6). Please add some information to the guide that after starting the installation it takes 2 minutes before anything shows up.
After the installation I was able to start CCS once. Then I choose to install additional compiler using the App Center. Then a restart was required. From this point on only the initial CCS screen is shown (before the workspace selection).
I uninstalled and reinstalled CCS, this time testing whether I am able to start a second time without updating, which was possible. Then I tried to update using [Help]->[Check for Updates]. After updating and restarting CCS it again only shows the initial screen, and then quits.
It seems there is an issue with the updater after the restart of CCS.
