Windows 8 and Signatures

Maybe I haven't been paying attention closely enough. Today, I finally installed Windows 8 for the first time. When I try to install a driver package that works just fine on Win 7, I get "the third-party INF does not contain digital signature information". I'm just using an INF and a SYS. Does Windows 8 now require a CAT file? -- Tim Roberts, xxxxx@probo.com Providenza & Boekelheide, Inc.

Does Windows 8 now require a CAT file? And the answer, empirically, is "yes". -- Tim Roberts, xxxxx@probo.com Providenza & Boekelheide, Inc.

Does Windows 8 now require a CAT file? Tim, is there a CatalogFile= statement in the inf? --pa

I added one and created the CAT file, and now everybody is happy. -- Tim Roberts, xxxxx@probo.com Providenza & Boekelheide, Inc.

RE: Windows 8 and Signatures

This is by design and here is why: In win7, you could import a driver package with a signed sys, an INF into the driver store. When you then installed the driver, you could only load the driver after answering the scary red dialog saying the driver was unsigned/untrusted. For the driver to load, code integrity has to be disabled, so if not current disabled during install, upon reboot. Without disabling CI, the install fails with the driver failing to load. In other words, a developer scenario. So, now importing a driver package in to the driver store will use CI to validate the package upon import to prevent the immediately !ed out device. CI validation will follow the current bcd settings. If you boot with CI turned off and import a package with no cat, the will succeed and the driver will load (assuming a successful install). If you boot with CI turned on, import fails (as you saw) because the package cannot be validated. d
