Windows 10 Software Installation and Disabling Signed Driver Enforcement

Unlike previous versions of Windows operating systems, Windows 10 imposes strict limitations on driver signing. Because of this, unsigned drivers require extra steps for installations.

NB: Be aware you will have to complete these steps for each PC you wish to use that connects with the laser machine as Windows 10 will automatically have signed drivers in place to cause these restrictions.

NOTE: You will need to restart your PC several times during the course of these steps and instructions so it is recommended to have this guide printed off prior to starting. For easy reference, here is a PDF copy.


For the installation, you will need:

  1. Your original software installation disk (this will have been provided on the day of delivery / setup of your laser machine). If you don't have your existing software installation disk, you may be able to find a copy of the software available for download from our website here. To access this you will need to have registered for a free account, and logged in.
  2. The syscfg.ini (system configuration) file that is on the PC currently driving your laser machine. You will also have been advised during training to keep a backup of this separately, so you may have a duplicate copy stored separately (in case your computer crashed).


You must comply with the following three steps BEFORE beginning this process.

  1. Turn off the laser machine.
  2. Disconnect the laser machine from the PC.
  3. Remove the USB software dongle from the PC.


You must allow each step to be fully completed before proceeding to the next instructions.

  1. Install the laser software as standard (run the exe file), allowing it to keep all default settings.
    The software is located on your disk in the location: Install Software > Install > Setup.exe
    Alternative, find the Install folder in the downloaded copy of the laser software.
    Only proceed once the software has fully installed.
      NOTE: if your software has been run previously on a computer, complete this step:
    Go to the C drive of the PC which has been running your laser and locate the Easycut/Lasercut folder.
    Copy the syscfg.ini file from the root of this folder and use this file to replace the default syscfg.ini file in the Easycut/Lasercut folder on the new Windows 10 PC (located in the C drive).
  2. Enter the start menu and click on power icon in the lower left of the screen. While the computer is restarting press the shift key and right click the mouse.
  3. When it asks you to choose an option, select the Troubleshoot option.
  4. Select Advanced options.
  5. Select Startup Settings.
  6. Click Restart.
  7. After restarting your computer the second time, choose Disable driver signature enforcement from the list below by typing F7 on the keyboard.
  8. You will now be able to install drivers normally, however when Windows displays the corresponding warning message, click Install this driver software anyway.


If you continue to get a communication error message, complete the following steps with both the USB dongle and the laser machine connected to your computer:

  1. Open the Device Manager (press the Windows key + X or right-click on Start to open the Power User Menu. Select Device Manager in the menu).
  2. Look for the EZ USB FX device (this should be found under Universal Serial Bus controllers). Right click on this device and select update driver software.
  3. When asked, opt to manually search for the device and point it to the Universal Serial Bus device.
  4. Click OK/Yes/Accept for all message windows that open.

The software should now run correctly.
