Disable Digital Signature Enforcement for 64bit WIN 7 8 10

Disable Digital Signature Enforcement for 64bit WIN 7 8 10

If the driver need be installed in 64 bit Windows System, it need have digital signature. While some driver don’t have digital signature and the PC can’t install this kinds of device. If you want to install this device in 64 bit Windows System, You need disable digital signature enforcement.

Our some equipment need disable signature enforcement, such as LMS-6000, LMS-7000 and LMS-9000 series spectroradiometer.

1. For the 64 bit WIN7, We have a small program in the CD, like the picture below. We can disable digital signature by the CD.


2. 
   
   The program named as below. Double click it.

3.  Then click ‘Next’



4. Click ’Enable Test Mode’ and go ‘Next’



5.  Restart your PC



6. For the 64 bit WIN8 & WIN10. We can disable the digital signature on the PC directly. First hold down ‘Shift’ key and then click ‘Restart’ as below picture.



7.  Enter ‘Troubleshoot’



8. Enter ‘Advanced options’



9.  Enter ‘Startup Settings’



10.  Click ‘Restart’



11.  Press ‘F7’
