Copied from Another user at the HIBY USER GROUP on Facebook, around July 18 of this year.
Look up "how to DISABLE DRIVER SIGNATURE ENFORCEMENT" in google. I found a simple method to disable until the next boot doing the search. Phil,another Hiby User offered this method that I had difficulty foillowing, But did learn that the "digital signature" problem
Once disabled the process works.
IF it does not, please contact Hiby Customer Service. I am neither a Hiby, nor a computer expert.. just trying to help...
Thanks, this worked for me and I was able to install the 1.4 update on my R3 Pro Saber!
Windows 10 users: Note that the driver does not come with a signature file. Thus, you may have to override the driver signature check within Windows.
More specifically, if you see the error:
"The third party inf does not contain digital signature information"
after Step 6 in the PDF or after you've attempted to install the driver via the .inf file, then you'll have to take the additional steps below.
GUI TO DISABLE DIGITAL SIGNATURE CHECKING:
1. Click START and type RECOVERY OPTIONS (not Recovery Control Panel)
2. Click ADVANCED STARTUP and let it reboot
3. After boot, click on ADVANCED OPTIONS > STARTUP SETTINGS
-- (Note that you may have to enter your 48-digit Recovery Key, depending on your security settings) --
4. Then select DISABLE DRIVER SIGNATURE ENFORCEMENT from the list
After this, you'll be able to load the driver correctly so that you can install the recovery image, which will allow you to (finally) install the update.
