Chromodo error message when running

I got the following error message when trying to run the Videostream for Google Chromecast app: “Native client (NaCl) plugin is missng.” “Your Chromium build doesn’t run Googles NaCl!” What to do. ???

Just a long shot from. What happens when you copy nacll64.exe, nacl_irt_x86_32.nexe and nacl_irt_x86_64.nexe from the Chrome installation folder to the CD installation folder? When running a 32 bits version of Windows nacll64.exe may be named differently like nacll86.exe nacll32.exe,
