How to Install ARS-USB Driver in Windows 8

Installing ARS-USB driver in Windows 8 can give problems as the driver is not “digitally signed “, ie Windows 8 does not see them as Windows 8 drivers. If you try and turn off this facility by using:

 

  • bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
  • bcdedit.exe -set TESTSIGNING ON

 

In the command window you can get back error message to say you cannot modify this setting due to Secure Boot Policy. You will have to go into BIOS and switch this off. Some PC you will be able to get into the BIOS on start-up by hitting function keys ( look in your PC manual ) then go to Security and follow the details from section 10 below. Most late PC will not allow this and you will have to follow the procedure below.

Hope the above helps, I cannot be responsible for any errors in the above write up its just a guide, it may be different on other machines please check yourself, but it gives you an idea of what needs to be done to install unsigned drivers. Please read all screens as you proceed and BE VERY CARFUL WHEN IN BIOS AND DOUBLE CHECK before to executing a command.
