All: I am having an issue trying to get an AVStream driver to install on win2k. The driver and inf work fine uder XP. The driver has an .X86NT specific section. The hardware install wizard says that "No appropriate driver could be found..." - even when I browse to the .inf manually. A setupapi log reveals that DIF_SELECTCOMPATIBLE... is failing. It also reveals that the device ID specified in my inf matches the device it finds in my inf. This works fine under XP. ------------------ Setupapi.log excerpt ------------------------- Searching for hardware ID(s): pcmcia\core_sound-pdaudio-cf-bf7d,pcmcia\core_sound-015d-4c45 Enumerating files c:\pdaudio\*.inf @ 11:59:58.208 : Opened INF "c:\pdaudio\PDAudio2.inf". @ 11:59:58.208 : Verifying file: c:\pdaudio\PDAudio2.inf using key: PDAudio2.inf in catalog: -. @ 11:59:58.218 : Verifying file failed with error: Error 0x800b0003: The form specified for the subject is not one supported or known by the specified trust provider. @ 11:59:58.228 : The file (c:\pdaudio\PDAudio2.inf) is not digitally signed, ignoring driver date. @ 11:59:58.228 : Found pcmcia\core_sound-pdaudio-cf-bf7d in c:\pdaudio\PDAudio2.inf; Device: Core Sound PDAudio-CF; Driver: Core Sound PDAudio-CF; Provider: CoreSound; Mfg: Core Sound; Section: PDAUDIO @ 11:59:58.228 : Decorated section name: PDAUDIO.NTx86 @ 11:59:58.228 : Device install function: DIF_SELECTBESTCOMPATDRV. @ 11:59:58.228 : Executing class-installer.
