Yes, the drivers have been certified in versions 1.7R14 and later.
Older versions of LogTag Analyzer used the unsigned drivers, and we strongly recommend you update your software to the latest version. Functionally both drivers are identical, which is why they will not be automatically installed when you upgrade from a version prior to 1.7R14. You may still upgrade your drivers to the signed version by selecting the optional hardware upgrade (FTDI USB interface) as part of the Windows Update feature. If you wish you can also update the drivers by selecting “Update Driver” through the Windows System Device Manager.
Please note this needs to be completed separately for every USB port with an interface connected.
You must have at least Windows XP or Windows Server 2003 Operating Systems installed for the drivers to be available through Windows Update.
