How can I update Google Talk freely?
just press button "Download Google Talk" at Software Informer site
after downloading /upgrading Gtalk for Vedio Chat. no result coming.
Unfortunately, Google Talk has been superseded by Hangouts and you can't update it anymore. Hangouts is a free of charge program developed by Google that has the same main features like Google Talk. If you have issues installing and running Hangouts, use the contact information from the official web page to get in touch with the Support team.
