This came from the driver CD that came with a cheap CH341 based USB to Serial adapter that had numerous other drivers on the CD as well. This is the correct driver for the serial adapter, and it includes drivers for Windows 7 x64. It also seems to have drivers for Windows 98, 2000, XP, 2003, Vista, and Server 2008 as well.
