# 0xC004F063: Required OEM license missing (no BIOS marker)

> Source: https://karincalisans.com/en/windows-error-codes/0xc004f063/ · Updated: 2026-08-28 · Publisher: Karınca Lisans

0xC004F063 means the OEM key you entered could not find the manufacturer marker (SLIC/OEM table) it expects in the computer's BIOS/UEFI. OEM keys are bound to devices pre-installed by the manufacturer; entering one on a different or custom-built PC produces this error. The fix is a Retail or MAK key for this machine.

## Most common causes

- An OEM key was entered on a custom-built PC without a manufacturer marker
- The motherboard was replaced and the OEM marker in the BIOS no longer matches
- A BIOS update or reset removed the OEM table
- The key came from another manufacturer's device

## Step-by-step fix

1. Check the channel line in "slmgr /dlv" output in an elevated Command Prompt; OEM_SLP or OEM_COA means the key is OEM type.
2. On a branded device (Dell, HP, Lenovo etc.) restore the manufacturer's official BIOS update; the OEM table returns.
3. On a custom-built PC an OEM key won't work: obtain a Retail or MAK Windows key and install it with "slmgr /ipk KEY".
4. Activate with "slmgr /ato"; if that fails, try phone activation via Windows + R → "slui 4".
5. If you bought the key from a seller, send them the error code — invoiced sellers exchange it for a type that fits your device.

## Frequently Asked Questions

### What is the difference between OEM, Retail and MAK?

An OEM key is bound to the manufacturer's device and motherboard; Retail is used on one device but can be moved to another PC; MAK is an online-verified, permanent and economical volume key. See our OEM vs Retail license guide for details.

### I replaced the motherboard — can I recover my old OEM key?

Usually not: an OEM license lives with the original motherboard. A new motherboard needs a Retail or MAK key.
