With Windows Server 2008 or higher ContaCam needs Desktop Experience installed on your server machine. It's better to install it before installing the camera drivers:
A. Install Desktop Experience
- Click Start, click Administrative Tools, and then double-click Server Manager
- In Server Manager, click Add Features under Features Summary
- In the Add Features Wizard dialog box, make sure that the Desktop Experience option is selected
- Click Next, and then click Install
- After the installation process is complete, click Close, and then close Server Manager
Note: After you install Desktop Experience, you have to restart the computer
B. If ContaCam is not working re-install the camera drivers
C. If ContaCam is still not working get DirectX from here and install it
