### Microsoft Windows prerequisites

Arithmethon requires an OpenGL ES 2.0 compatible graphics card and driver.

Most newer Windows PCs running Windows 7 and newer can be expected to have this and be compatible.

Some older computers (Windows 7 en Vista) have a built-in graphics chip with old drivers that don't support OpenGL ES 2.0

In some cases, a newer graphics driver can be installed. If no newer driver is available, a PCIE graphics card and driver can be installed (for example NVidia of ATI).

Arithmethon has a good 'Uninstall' utility that cleanly removes it from any Windows PC that does not work.
