Installing Lasercut 5.3 on Windows 10

Your laser cutter driver file will not install on Windows 10 as it is designated unsigned by Microsoft. On previous distributions of Windows, a click-to-continue button allowed the installation of unsigned drivers. In Windows 10 you must enter a special mode similar to safe-mode in older Windows distributions. To enter this mode requires a shutdown/restart of your computer. Make sure you have closed and saved any work or applications before restarting your computer. You must be an administrator user to complete this installation.

Click the Windows icon (usually at the bottom left of your screen), click on POWER, then click on RESTART whilst holding down the SHIFT key.

This will restart your computer and may take a few minutes. It will load the following screen:

Click on TROUBLESHOOT.

Click on ADVANCED OPTIONS.

Then click on STARTUP SETTINGS.

The STARTUP SETTINGS screen shows you the options you will be allowed to change once you have clicked on RESTART. This will again, reboot your computer to the following screen.

Now using the keyboard press F7. This will "DISABLE DRIVER SIGNATURE ENFORCEMENT" and allow us to install the unsigned laser cutter driver. Pressing F7 will reboot your computer to the usual Windows login screen. This may take a few minutes.

Once you have disabled driver signature enforcement installation is the same as for Windows 7. Instructions for which can be found here
