TPMAPI_E_INVALID_CONTEXT_PARAMS
TPMAPI_E_INVALID_CONTEXT_PARAMS is a Windows TPM API result. It indicates that one or more parameters used to create or configure a TPM context are unsupported or inconsistent.
What to check for TPMAPI_E_INVALID_CONTEXT_PARAMS
- Initialize the context with documented defaults and add optional parameters one at a time.
- Check pointer, buffer length, flag, and version fields for mutually incompatible combinations.
- Ensure context parameters match the TPM API version available on the target Windows installation.

Diagnostic interpretation
This result has the HRESULT value 0x80290115. AllStat records the condition as “One or more of the specified context parameters was not valid.”.
Evidence to capture
- Capture any IErrorInfo text, activity identifier, event-log entry, and subsystem trace that mentions this result or the tpmapi / context / params operation.
- Preserve the first failure in the call chain; a later HRESULT can describe cleanup rather than the original tpmapi / context / params condition.
Retry and recovery
Do not retry an unchanged request after TPMAPI_E_INVALID_CONTEXT_PARAMS. Change the confirmed precondition first, then rerun the original path and record the next result and final object state.
