Q1: How to update my CN900 V2.03.3.40S to the newest version V2.21.3.50SC?
A1:There are two methods. (1) Browse the official website and download the newest software to directly update. (2) For regular customers, active (get authorization for) ID46 function, and your CN900 software will be the newest version. Please be noted that the version number can display only after ID46 function is activated.

If the software V3.19 is installed in the computer but the driver can not be installed automatically, how do we solve this ?
Pls open "C:\Program Files\HRT\AK90\Drv" and install the driver.
