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

I bought a Sabrent USB-DH88 usb video graphics display adapter, which is using displaylink Display Adapter (0360).
After installed the software, on my windows 7 bits desktop machine. it shows up as
"Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"

I tried to downgrade/upgrade to different version from displaylink (7.4 M0, 7.2 M0, 6.2 M2, 5.6 M1). it shows up the same result.
I did try the "Ultra USB Graphics Adapter Model#: U12-40889". it has same (0360 chip set). it shows up the same result as well.
and When I tried on on 32 bit windows 7 laptop, everything is working just fine.

Any suggestion? or should I return the product?
