Disable Digital Signature in Windows 7, 64 bit
Microsoft enforces a “Digital Signature Requirement” on all users of 64 bit version of Windows 7 and Vista. If you try to use any product driver that was not certified by Microsoft, you can still install it but Windows 7 - 64 bit won’t let you run the driver.
There are two ways to disable it:
Go to Start Menu and type "cmd.exe" in the Search Bar and press <Enter>. (Remember you must be logged on as Administrator)
OR you can go to "All Programs", then "Accessories", right-click on "Command Prompt" and choose "Run as administrator".
1. Now type the following and press <Enter> after each line:
bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
bcdedit.exe -set TESTSIGNING ON
2. Restart your computer
3. This will disable your Windows 7 driver signing.
If this did NOT work for you, here is another way to disable Windows 7 driver signing.
1. During boot-up, continuously press <F8> to get to Advanced Boot Options. Note: On some systems, you need to first press <F2> to go into Boot Menu, then press <F8> to reach Advanced Boot Options.
2. When the menu appears, use the DOWN arrow key to scroll to “Disable Driver Signature Enforcement.”
3. Press <Enter>.
4. Continue the boot process.
5. After your computer has completed the boot process, please install the drivers per the included instructions.
