--- Comment #2 from piyush piyushgarg80@gmail.com 2013-06-08 11:20:34 CDT --- I see the files at that location but the same errors are also coming while running. So do not know whether installation terminates abruptly or not. (In reply to comment #1)
I get errors in the terminal as well, but the installation succeeds. Do you see files in C:\users\piyush\Local Settings\Application Data\Viber\ ?
