Driver Installation Guide - for drivers that Window's couldn't install directly (instructions for Window 7, but also works on other versions)
On the FTDI Chip page, scroll down to the Processor Architecture grid. The first line is for Windows operating systems 7-10 (see the * below the grid for specific OS's). In the Comments column on the right, click on the setup executable. Download this utility and follow the on-screen prompts to extract and install the software. Administrative privileges may be required.
On the page, select PC Devices, then choose the driver. 26886 WinXP-Vista-7-8 for older adapters (blue and sliver) or 26887 WinXP-Vista-7-8 for newer ones (all black). If your computer is Windows 8 or 10, make sure that you have USB/Serial adapter that is compatible with Windows 8 or 10. The drivers shown here are compatible with both. Administrative privileges may be required.
