After installing Security Center, you might have to install some Microsoft hotfixes for Security Center to run smoothly.

What you should know

The following scenarios require that you install a Microsoft hotfix:
  • You log on to Config Tool or Security Desk after installing Security Center and you receive the message: "A necessary dependency for this application has not been found on the system. Video stability and performance are not guaranteed without the hotfix KB2494124/KB2468871".


  1. Close Config Tool and Security Desk.
  2. Download the required hotfixes from the Internet:
