As I can see, these are two different applications. Because of that, in Add or Remove, they're listed as 2 separate programs. If they're installed correctly, you can access both of them from Start > All Programs. There is the case, where these two programs have been merged one into another. This allows you to access the other one within the first application you've installed.
Additionally, one program might act or be a replacement for the other one. If you want both applications installed, create another Windows user from Control panel and then right click one application and select RUN AS. This will install the application separately.
