Our technical support team has tested FinishLynx version 8.2+ and determined that the software is fully compatible with Windows 8 and 8.1. However, some Lynx users have experienced compatibility issues problems with their USB-to-serial adapters. In some cases, out-of-date USB drivers may cause problems on Windows 8 devices – making them unable to connect properly. Fortunately, this is a very easy fix. Simply download the latest device drivers for your model of USB-to-serial adapter and install them on your Windows 8 devices. This will ensure compatibility on race day. The latest Windows 8-compatible drivers can be downloaded from manufacturer websites. We’ve also included some instructions below for some adapters commonly used with FinishLynx systems. Please update your USB drivers if you use Sabrent, Prolific, or ATEN serial converters. See the directions and downloads below.
