How to Disable Driver Signature Enforcement to allow installation of Windows 7 Printer Drivers on Windows 8

Are you having trouble installing DNP, HiTi or Mitsubishi Windows 7 printer 

drivers on a Windows 8 PC? We have a solution for you.

On Windows 8 (64 bit) operating system, you must disable the Driver 

Signature Enforcement to install the Win 7 (64 bit) printer drivers. Once the 

Driver Signature Enforcement is disabled the system will reboot, then you will 

be able to install the driver.

This is how you disable the ‘Driver Signature Enforcement’ on Windows 8 so 

you can install the Windows 7 printer driver*:


1. Open the Charms Bar in Windows 8 and select “Settings”:

2. Select “Change PC Settings”:

3. Select “General”:

4. Scroll to the bottom of the General page and select “Restart Now” under 

“Advanced Start-Up”:

5. Once the PC comes back up, select “Troubleshoot”:

6. Select “Advanced Options”:

7. Select “Start-Up Settings”:

8. Select the Restart button:

9. Press either the F7 key or the number 7 key from your computer keyboard. 

This disables the Driver Signature Enforcement, which will allow you to install 

a printer driver. After pressing either key, your computer will reboot:

After rebooting, log in as normal and go to the Control Panel. Select “Devices 

and Printers” and you are ready to install the Printer Driver.

* All these steps have been tested on the 64 bit version of Windows 8.
