How to Install Driver with a cat file?
In Windows Vista and Windows 7 there a new utility for handling drivers setup call PnPUtil. It handles exactly this kind of work. Just copy all your driver relevant files(*.inf, *.cat, *.sys) to a directory on the target computer and use PnPUtil -i -a <InfName>.inf
Note: You will need to be in an administrator context to successfully use this tool.
You need to get an Authenticode signature, create a catalog file, and sign it with that. Microsoft decided that, for 64-bit systems, it will require the driver to come untampered from the vendor, by checking it signature.
(Note: This is not the same as WHQL, which tests the quality of the driver. Authenticode merely indicates that the driver hasn't been tampered with by some malicious user or virus; it doesn't say anything about what the driver does, so it's a relatively easy -- although pricey -- signature to obtain.)
Another solution is test-signing, if you don't plan on redistributing your program.https://technet.microsoft.com/library/dd919230.aspx
