"Windows cannot verify the digital signature(Code 52)" Error for 64 bits Windows 7

Hi, James,

Thanks for the reply.
I followed your instrustions.
1. Disconnect the adapter
2. Uninstall the DisplayLink software
3. Download and run the tool EndUserCleaner.exe
4. Restart the machine.
5. installed V7.4 M0
5. Plug in the adapter. it still shows up as "Windows cannot verify the digital signature for the drivers (Code 52)".

Before this, I did some google search. Tried with the workaround posted on microsoft website as the link below.
"Boot into Advanced Boot Options and disable driver signing checking."
It seems the USB display Adaptor works fine after this. Although, every time when I reboot the machine, I have to disable "driver signing checking". it's kind of annoying.

Hello James,

I'm having the same issue that tigertanghao, I already used the "user clean tool" and installed the latest version 7.5 M1 but still is not working.

Any update that you can suggest to fix the issue will be great.

Thanks.
