Before you begin to install Vision, verify that your network and classroom computers meet all of the following system requirements. You must also have a valid serial number to activate Vision, as well as valid serial numbers to activate any plug-ins you wish to use.
You can install a 30-day evaluation version without a serial number in order to test Vision and all plug-ins.

System Requirements
The network must have the following minimum configuration:

•Wired Network: 10 Mbps full duplex; 100 Mbps or higher recommended.
•Wireless Network: 802.11b; 802.11g recommended
•Peer-to-peer name resolution enabled (e.g., DNS or other name server)
The classroom computers must have the following minimum configuration:

•Operating System: Windows 7 Professional or better (Vision 6.9.0 or higher) ; Vista Business or Ultimate (version 6.5.0 or higher); XP Professional; Windows 2000 Professional (up to version 6.8.3); and Windows 98 (student only up to version 6.5.2). 64 bit operating systems are only supported after Vision 6.9.1. Vision supports classrooms with a combination of supported operating systems, but only if they are running the same version of Vision.
•Processor: Intel® Pentium® III processor or equivalent; 500 MHz or higher
•Memory: 64 MB RAM; 128MB and higher recommended
•Hard Disk: 50 MB of available hard-disk space
 •Video Display: Any 100% VGA compatible graphics adapter supported by Windows (the latest drivers from your computer manufacturer are highly recommended)

 NOTE: Vision requires that all connected computers be able to communicate with one another by computer name. If network settings on a computer are changed, this may disrupt name resolution and cause Vision connections to fail. Ping a student computer by name from the teacher computer, and then ping the teacher computer by name from a student computer. If the ping fails, contact your network administrator. If the ping succeeds but Vision does not function properly, contact Technical Support.
