How do I ensure a smooth installation and operation of CyberLink YouCam?

Apart from the system requirements, we recommend you follow these steps:

1. Close all other applications, including anti-virus software and instant messenger programs
2. You must completely shut down (not only hide in the system tray) your instant messenger software, such as Windows Messenger, Yahoo Messenger, AOL Instant Messenger, or Skype, before you can proceed with the installation. This is to allow CyberLink YouCam to properly install the video communication service that is necessary to enable the video effects during your video webcam session.
3. Microsoft DirectX® 9 runtime library must be installed in advance. CyberLink YouCam requires Microsoft DirectX® 9 installed runtime library on your system for certain CyberLink YouCam functions to run properly. The CyberLink YouCam CD setup program will automatically install the DirectX 9 runtime library. But, if you purchase the Internet download version or the free trial version, you have to download this module from the Microsoft Web site or from other Web locations. Microsoft DirectX® 9 can also be found at the Microsoft DirectX® 9 download page.
