Hello. You are running Windows 8?
You need to navigate to your applications.
Hit the windows key on your keyboard, you should see the start screen, where Lightroom and Photoshop should be. You can right-click on them to pin them to the task bar.
You can't start them from the CC app. They are installed as any other program in your Start menu.
BTW, isn't Windows 8.1 free for Windows 8 users? it might make everything easier, no?
