| Problem | Likely Cause | Solution | |--------|-------------|----------| | | The INF is a component, not a full driver package. | Use Device Manager’s “Have Disk” method instead of right-click Install. | | “This INF contains no driver information for the device” | The INF is for a different device or wrong architecture. | Verify you have the correct 32/64-bit driver and that the hardware ID matches. | | Windows says “Third-party INF does not contain digital signature information” | The driver is unsigned or the signature is invalid. | If you trust the source, temporarily disable driver signature enforcement (advanced startup options). For testing, use bcdedit /set testsigning on (revert after). | | Device still has yellow exclamation after install | Conflicting or residual driver. | Right-click device in Device Manager > Uninstall device > Check “Delete driver software” > Reboot > Reinstall. | | Install seems to work but device doesn’t function | Missing companion files (.sys, .dll). | Ensure all files from the original driver package are in the same folder as the INF before installing. | how to install inf driver
