SL_E_CHPA_INVALID_PRODUCT_KEY
SL_E_CHPA_INVALID_PRODUCT_KEY (0xc004c004) is a Windows Software Licensing activation-service code. The activation service rejected the product key as invalid for the activation request. Verify the edition and key source before entering another key; a key for a different product or channel will not activate this installation.
What to check
- Check the installed Windows edition in Activation settings.
- Ensure the product key is complete and came from Microsoft, the OEM, or the rightful licensing organization.
- Do not rely on key generators, shared keys, or unofficial activators.
