TPM_E_VERSION_NOT_SUPPORTED
TPM_E_VERSION_NOT_SUPPORTED means the TPM or Platform Crypto Provider does not support the version required by the operation, key format, policy, or protocol.
What to check
- Read the TPM specification version and vendor/firmware details before changing application settings.
- Verify the minimum TPM and Windows version required by the workload.
- For a mixed fleet, implement capability-based behavior instead of assuming every device supports the same TPM feature set.
