Here's a smart trick that you can follow to run multiple instances of Google Talk desktop client 😉
- Create a shortcut for Google Talk on your desktop. [You can right click on GTalk in your program files and choose Send To -> Desktop ]
- Now on your newly created Gtalk Desktop Shortcut, right click and choose 'properties'.
- In the target section of properties - add /nomutex at the end of the path. For example, your path would look like this - "C:\Program Files\Google\Google Talk\googletalk.exe" /nomutex ;-)
- Double click on this icon and launch your first instance of Gtalk. Then double click on the same icon again and launch another instance. You can login to separate accounts from these two instances.
Enjoy 😁
