Problem installing Google Talk on Vista

Recently I faced the following when installing Google Talk in my Vista machine:

"The new version of Google Talk cannot be installed because you are running an older version of Google Talk that is not compatible with Windows Vista. Please uninstall Google Talk as Administrator to remove the incompatible version and re-install Google Talk from http://www.google.com/talk."

Have tried many ways to overcome this problem but failed so far ...

Today I have managed to install it. The treat was quite simple ... Just download an old version of Google Talk (you may get one from: http://www.oldapps.com/google_talk.htm). After that uninstall it. Go to Google talk page, download again the latest version and install it. This is how I did it.

Anyway, not sure if this will work on your computer or not. Let me know if you have tried it. Good luck!
