What driver should I use?

Customers on Windows 10 or 11 should use this new version v5.27.0

Customers on Windows 7, 8, or 8.1 should use v5.12.0

Customers on older versions of Windows can use v1.67, but it doesn’t support all products.

The previous version (v5.12.0) added compatibility with Windows 10.

This can be used on the following operating systems in both 32bit and 64bit:
