If you have installed DataCAD 8.0, 8.5 or 9.0 on a computer running Windows XP, you need to download and install the latest hardlock driver. It is available here:

http://www.datacad.com/update/update_hardlock.htm

If you install the newer driver and still receive the same "Cannot open hardlock driver" error message when you try to run DataCAD, you need to manually remove all hardlock drivers, then reinstall the latest one.

Exit all programs and open the Control Panel from the Windows Start menu. Open Add\Remove Programs.

Locate the "hardlock device driver" or "hardware key device driver" and choose Remove. Select the Custom option and choose Select All then Next each time you are prompted. Click Finish to complete the process.

You may now reinstall the latest hardware key driver that you downloaded from our Web site.
