I just got a new computer, or upgraded my operating system, and now my hardware lock isn't working.


One of the following error messages appears when I try to launch Chief Architect: 

  • HASP Device Driver Installing the Device drivers failed. Failed to start the Aladdin Device Driver. Failed to start a service in the Service Control Manager Database.

  • Windows cannot load the device driver for this hardware. The driver may be corrupted or missing.

  • No Appropriate Hardware Lock Was Found.

How do I resolve this issue?

If your version of Chief Architect is running on a newer operating system than it was supported on then following the steps in this article may not resolve the issue.

If you do not know which operating systems your particular version of Chief Architect is supported under, then please see the Related Articles section at the end of this article for a link to the System Requirements.

The Mac version of Chief Architect cannot be used with a hardware lock.

Chief Architect X2 and newer versions utilize Software Lock Security by default, instead of a hardware lock security device. To learn more about Software Security please visit the Chief Architect Software Security article listed in the Related Articles section.

If you are using an Academic network USB hardware lock license, please review the advanced troubleshooting steps in the Network Installation Guide, located in the school's Digital Locker by signing into the website.


Downloading and installing an updated hardware lock driver may resolve this issue, if you are running your version of Chief Architect on the version of Windows that it was designed to run on.

To install the new driver

  1. In your Windows Control Panel, access Uninstall or change a program.

    Depending on the view you are in, you may see Programs and Features instead.

  2. Search for the HASP Device Driver or Sentinel Protection Installer, depending on your version of the hardware lock. 

    • If found, click on the HASP Device Driver or Sentinel Protection Installer, and select Remove or Uninstall.

    • If the Device Driver is not found in Uninstall or change a program , proceed to step 3.

  3. Click the link below to go to the latest drivers page for your hardware lock, then download the latest driver in the list. Once the driver is successfully installed, shut down the computer and reboot it.
