Title: Can't install drivers
Post by: luismc on January 30, 2014, 04:44:25 pm
Hi,

I can't install drivers in Windows 8 x64
I plug the OLS at USB input
I give mchpcdc.inf file to windows when asked
Then I get an error:
"... Windows found an error ... Communications Port ... Hash of file is not present in .cat file specified. It is possible that file is damaged or manipulated"

Thanks in advance

I believe this is the signed driver problem that has been bugging Windows 8 users. Can you turn off the driver signing and try again?

Hi tayken,

You are right!
Drivers was successfuly instaled when signed driver was disabled.

Thank you very much !

Hello,
I have the same problem, it seems quite common.
I enjoy the solution, but, to be honest, I don't know how to "disable signed driver", the wizzard didn't offer me something like that.
Kind regards,
Helmut

I am following the steps as indicated at "Get started with the OpenBench Logic Sniffer on Windows".  When I go through step 3 "Install drivers" I get a windows message saying that installation of the driver failed. I've tried 3.08 and 3.07 versions and neither of them worked. Can anyone help me? How can I "disable signed driver"?
PS: My system is win8 64bits.
