Hi:
I have a question need your help,Now, We already made a driver(include
SYS,INF)
The driver run well on Windows 32bit OS(Window2000~WIndow7).
But IT can not be loaded on WinX64 OS.The device Manager always show that
there are no Digitally Signed at Digital Signer.
When i switch system work mode to disable enforcement digital signed Check
mode,The Driver work well.
SO i bought a signature from VerSign, Use SignTool to make digital signature
on SYS file.
SYS file can be seen that there is a correct signature. But I put the new
SYS into Drivers directory. restart OS
The device manager show no digitally signed yet.
There is a yellow "!" at the head of device name.
Could you tell me what happen to this SYS. How to let OS load our driver.
Thanks.

This group is not really programmer oriented, but if you go to
http://www.microsoft.com/whdc/winlogo/drvsign/drvsign.mspx Microsoft has
lots of information about Driver Signing Requirements for Windows.
