I have CyberLink MediaShow 3 installed on my computer already. Will installing CyberLink Media Suite 9 remove it from my computer?

CyberLink MediaShow 3 and 5 are very different software. If you have CyberLink MediaShow 3 installed on system already, it will not be removed during installation. However, if you have CyberLink MediaShow 4, it will be removed during installation.
