Yes, you can use KIK on your desktop PC, but not in native mode. This means you will have to install Bluestacks in order to run the application. Bluestacks is a virtual environment that's running Android operating system. You can install Android apps just like if they were on an Android phone.
Make sure you have a phone next to you to activate the account.
