When automatic methods fail, manually identifying the exact hardware ID guarantees a perfect driver match.
Most modern versions of Windows 10 and Windows 11 already have the database for the 08 18 chipset built-in. You might not need a manual download at all.
Cause: You downloaded the 32-bit driver for a 64-bit OS, or vice versa.
Fix: Re-download the driver explicitly labeled "x64" for 64-bit Windows or "x86" for 32-bit.
