Windows 7: Windows refusing to run a beta driver.

swarfega · 27 Feb 2009

I am trying running a beta version of a driver for a Nova Tuner stick but windows reports:

Quote:

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 know about the disable digital signature enforcement option in F8 menu but its a bit of a hassle having to reboot every time you want to use the stick. Is there a way to make windows accept this driver permanently?

Hi swarfega,

Have a look at the advanced options with EasyBCD - I think the option to not require signed drivers in 64Bit is a permanent setting

I downloaded easyBCD and ticked allow unsigned driver installation on vista 64-bit edition and hit apply and then reboot but the driver is still not working.

Does it work using the F8 option?, if not only other thing I can think of is that it is signed but either the file or the signing is corrupt, you may want to d/l the driver again, from a different source if possible

It did work with F8 option. Trouble is im pretty sure its unsigned as its beta and the moderator on the forum said they were waiting for WQHL cert in the next week or so.

The problem there is the present 1.7.2 version is now seeing a new 2.0 beta replacement that will address some of those problems for 64bit and others for Linux ext 3, 4 support problems. [ame=http://www.neosmart.net/forums/showthread.php?t=642]EasyBCD 2.0 Beta Builds - The NeoSmart Forums[/ame]

I downloaded the beta version and WMC still refuses to find my tuner :/

Try this:

open an elevated command prompt and type:

bcdedit -debug on

Restart and see what happens.

To undo the above, open evelated command prompt and type:

bcdedit -debug off

Hope it helps

Hi Swarfega,

When you say WMC doesn't see the tuner Is it showing in the Device manager?
I have heard of a few people having problems with WMC and tuners in x64, and there have been a few patches from windows update including at least one specific to Europe & UK.

Not something I actually use so can't really help with specifics but it could just be that the drivers are just not ready yet

and you'll have to wait for the certified ones

yeah its not showing in device manager. I looked at adding in hardware but ms in their thoughtfulness seem to have removed have disk option in order to install the .inf file.
