A friend has just downloaded and installed Chrome for Mac OS (current version 51).
When they click to open Chrome the icon appears briefly in the dock, then disappears and Chrome closes.
The behavior is replicated if you try to launch Chrome form the command line using
/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome
They get an error
Failed to create /Users/NAME/Library/Application Support/Google/Chrome/SingletonLock
If they run with sudo
they are able to start Chrome.
sudo /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome
How can we fix this? We've tried reinstalling Chrome and the problem persists.

We fixed this by deleting the lock file in
~/Library/Application\ Support/Google/Chrome/SingletonLock
and everything else in the profile runningSeems related to the Chrome is not opening on the Google Chrome Help forum.
