If you receive the following error when launching Session, and are experiencing slow graphical performance and screen redraw, you need to install the latest drivers for your video/graphics card from the manufacturer's website.

 


You can find the manufacturer and model of your video/graphics card in the Windows Device Manager.  The Device Manager can be accessed from the Windows Control Panel.




Double-click the "Device Manager" icon in the Windows Control Panel to open the Windows Device Manager.  If you get a "User Account Control" window, click "Continue".  Click the + next to "Display Adapters" to view your video/graphics card.



As you can see in the example above, this particular computer's video/graphics card is manufactured by NVIDIA, it's their GeForce Series, model 7300 DS.  You must download the drivers for your specific video/graphics card from the company that manufactures the video/graphics card in your computer.
