 Hi,

Thank you for posting your query on Microsoft Community.

From your issue description, I understand that you are unable to install audio driver Conexant 221 on Windows 8 64 bit.

Could you please answer the following questions so that I can help you in a better way.

1. Do you get any error message when you try to install this driver?
2. What is the model of the computer?
3. Have you made any changes to the computer prior to this issue?

I suggest you check the information given below.

A signed driver is a device driver that includes a digital signature. A digital signature is an electronic security mark that can indicate the publisher of the software, as well as whether someone has changed the original contents of the driver package. If a driver has been signed by a publisher that has verified its identity with a certification authority, you can be confident that the driver actually comes from that publisher and hasn't been altered.

Windows cannot install this driver
A driver that lacks a valid digital signature, or that was altered after it was signed, can't be installed on x64-based versions of Windows. As a result, you will only see this message if you are running an x64-based version of Windows.

As you are getting this message when attempting to install a driver, you should visit your device manufacturer's support website to obtain a digitally signed driver for your device and check.

Hope the above information helps.
Do let us know if you have any other queries pertaining to Windows in the future. We will be happy to help.
