Did you ever want to open two instances of Google Talk simultaneously? Yes, it is possible. You can infact open two instances of GTalk at the same time and log in into two different accounts. Here is how you can open multiple instances of GTalk at the same time:
First find out where your GTalk is installed. This would usually be:
C:\Program Files\Google\Google Talk\googletalk.exe
Once you have found out where your Google Talk is,
• create a short cut by right clicking on your desktop and choosing Shortcut
• Browse and choose the location of the file and add “/nomutex” in the end of the location. So your path looks like this
“C:\Program%20Files\Google\Google%20Talk\googletalk.exe” /nomutex
That’s it. Now click on your usual link to open GTalk. After you open it, log into it. Now click on the new shortcut that you created to open the second Google Talk.
