SL_E_CHPA_PRODUCT_KEY_BLOCKED
SL_E_CHPA_PRODUCT_KEY_BLOCKED (0xc004c003) is a Windows Software Licensing activation-service code. The activation service has blocked the product key. This is not a local configuration error that can be fixed by modifying Windows files or retrying activation with the same key.
What to check
- Stop using the blocked key and verify the purchase channel or organization entitlement.
- If the key was supplied by an employer or institution, contact its licensing administrator.
- If the key was purchased from a reseller, use the seller or Microsoft support process with proof of purchase.
