Getting Argyll/dispcalGui working under Windows 8.1 64-bit

by / Friday, 03 January 2014 / Published in Blog

If you upgrade to windows 8.1 64-bit, you may find that you cannot install argyll drivers for your colorimeter in a usual way.

To install them, you need:


  1. Disable Driver Signature Verification on 64-Bit Windows 8.1
    1. Press the Win + C keyboard combination to bring up the Charms Bar, then click on the Settings Charm.
    2. Click on the Change PC settings link
    3. When the Control Panel opens, switch over to the “Update & recovery” section
    4. Then click on the Recovery option on the left hand side
    5. Once selected, you will see an advanced startup section appear on the right hand side. You will need to click on the “Restart now” button
    6. Once your Computer has rebooted you will need to choose the Troubleshoot option
    7. Then head into Advanced options
    8. Then Startup Settings
    9. Since we are modifying boot time configuration settings, you will need to restart your Computer one last time
    10. Finally, you will be given a list of startup settings that you can change. The one we are looking for is “Disable driver signature enforcement”. To choose the setting, you will need to press the F7 key.
  2. Edit Argyll\usb\ArgyllCMS.inf :

    Find the two lines: (possibly lines 47-48)

    CatalogFile         = ""
    CatalogFile.NTAMD64 = ""

    And comment them by adding a semicolon at the beginning of each line:

    ;CatalogFile         = ""
    ;CatalogFile.NTAMD64 = ""

    Save the file

  3. Open Device Manager, select your colorimeter, choose Update Driver and select Argyll\usb\ directory under Have disk option.

Now your colorimeter will work with Argyll CMS under 64-bit Windows 8.1

Tested with ArgyllCMS v. 1.6.2
