Players encountering the Secure Attestation error 0x80190190 in Call of Duty, linked to Intel PTT and TPM AIK, now have a community-discovered solution. The problem occurs despite TPM and Secure Boot passing system checks, caused by mismatched Intel PTT intermediate certificates in Windows. By extracting the correct certificates from the TPM's non-volatile storage and installing them into Windows’ Intermediate Certification Authorities store, the certificate-chain error is fixed, allowing Secure Attestation to function properly. This fix is crucial for players blocked from launching the game due to this technical issue as of August 2026.
- Error 0x80190190 relates to Intel PTT / TPM AIK certificate mismatch.
- Fix involves manually installing correct certificates from TPM NV storage.
