Installing Az-Tech Rockeys in Windows XP

Windows 8, 7, XP (and Vista) is significantly different from other operating systems to date.  Note that hardware keys cannot be accessed unless drivers are installed.

Please note that keys with serial numbers starting at 2000 do not require drivers!

If your software is DOS, the driver is normally distributed on a CD with the software or on a separate "Drivers" CD. For Windows software, it is on the product CD. If you do not have this CD, you need to get the driver from the Interpex ftp site.

On older distribution CDs, you will find Azsetup.exe and perhaps InstDrv32.exe or InstDrv64.exe. Azsetup is for operating systems through Windows XP. InstDrv32.exe or InstDrv64.exe are early drivers specifically for Vista. Rockey4.exe is for all 32-bit and 64-bit Editions of Windows 2000, XP, Vista, Windows 7 and Server.

To get the newest driver, you need to download You then need to install it, restart your computer and then connect the USB key. Allow Windows to install the new hardware.

The new driver ( works with Windows XP and Vista. You can download it from the Interpex ftp site, the support directory. These drivers should work in Windows 2000 on.

USB/Parallel ROCKEY Installation:

 Please be sure to do the following: 

  1. Do NOT plug in the USB key!
  1. Install the Interpex software.
  1. Install the Rockey4.exe Az-Tech hardware key driver.
  1. Restart the computer.
  1. Plug in the USB key and allow Windows to install it automatically.
  1. The light on the USB key should come on and stay on. Older keys blink rapidly when being accessed but the newer keys do not. If it blinks continuously something is wrong.
  1. It should show up as "Felitian ROCKEY4", "Felitian ROCKEY4 USB" or "USB Key" in the Device Manager under Universal Serial Bus drivers.
If you have already connected the key and if Windows already "found new hardware" and installed it (thinking it knew what it was), you will have to go to the device manager to uninstall the device driver for this before installing Rockey4. With the key plugged in, right-click on "My Computer", select "Properties" then go to the hardware tab and click on the "Device Manager" button. Devices that are not working properly are shown in yellow. Find the device (see names above), right-click on it and select uninstall. Then disconnect the key and restart your computer. (Re)Install the Az-Tech driver, restart the computer and plug in the key.
If you are using a USB key, it has a light on it. When connected, the light should come on and stay on. When the key is accessed (when you run the software), the light will flicker on older keys but the newer keys do not do this. If the key is not installed properly, it will blink continuously and slowly.

If the key still does not work (the software does not see it), download and run Keyshow.exe to see if it can see the key and shows any diagnostics. Out of several hundred USB keys, we have had only two fail and both failures occurred in Golden, CO! So the likelihood of a key failing is remote but possible. We will replace the key if it fails and you return it.
