Make YFCAD software compatible with Windows 7. Upgrade your keylock driver now!

Upon the official release of Microsoft's new operating system Windows 7, YFCAD upgrades its keylock driver to a Windows 7 compatible beta version.

We suggest all users currently on Windows 7 platform to upgrade to this beta version, because earlier drivers have compatibility problems with Win7.

This driver is for InteriCAD series, KD Max, 3DShow, and BtoCAD. Other programs please contact your distributor or intericad@yfcad.com for more information.

Upgrade Instruction:

Step 1: Download from http://www.yfcad.com/download/yfcad_driver_whql_20091021.zip

Step 2: Make sure your software keylock is not connected to your PC or laptop.

Step 3: Extract the zip file, then run InstWiz3.exe as administrator.

Step 4: If you have earlier driver installed on your system, do uninstallation first as in the picture below.


Step 5: Run InstWiz3.exe as administrator again, follow the instruction to install driver.

Step 6: Connect your keylock to PC or laptop, wait for device to install.

Note: If you get no response when you insert your keylock to a PC, try another USB port at the back of your PC case.
