I have installed chrome canary along stable build on windows 7. Canary build loads perfectly, but stable version didn't launch. Is there any solution to run stable build without uninstalling canary build?
Run the stable version from the command line. It will print any errors back. The error message should help you figure out why it isn't starting.
Also, you might run the Task manager (Ctrl-Shift-Esc) and see if a zombie Chrome process is running on your PC. If so, use the TM to kill it and you should have no more problem.
