OSS_CANT_OPEN_TRACE_WINDOW
OSS_CANT_OPEN_TRACE_WINDOW (0x80093018) is an OSS ASN.1 runtime result for legacy trace window could not be created. The Windows-specific diagnostic trace window failed to open; the encode/decode operation may be secondary to an instrumentation setup problem. Because desktop/session identity and interactive availability is central to this condition, Microsoft’s HRESULT range and the OSS Nokalva return-code documentation should be read together. Start the investigation by recording trace flags and window handle inputs, then separate the encoded value from generated artifacts, call arguments, and the runtime package actually loaded by the process.
Similar names, different faults: OSS_CANT_OPEN_TRACE_WINDOW
This status does not establish that ASN.1 data is bad; it identifies failure in a legacy diagnostic presentation channel.
Where processing stopped
At the legacy trace window could not be created boundary, capture the first OSS function returning the value and note whether the operation was encode, decode, copy, compare, constraint validation, or trace setup. Preserve the selected PDU, encoding rules, and first Win32 error captured at creation time; otherwise an outer certificate or security wrapper may hide the useful codec result behind a generic failure.
Isolation sequence
- redirect diagnostics to a file or callback
- run under the same service/session account
- disable only tracing to prove codec behavior is otherwise unchanged
Facts that change the conclusion
- desktop/session identity and interactive availability
- trace flags and window handle inputs
- first Win32 error captured at creation time
Instrumentation
Where desktop/session identity and interactive availability can expose sensitive content, a hash plus a bounded structural excerpt is safer than the complete payload. Use trace flags and window handle inputs together with OSS module paths and versions logged once per process so packaging differences can be correlated without flooding normal diagnostics.
Completion check: the result
Use a trace sink appropriate for services and noninteractive sessions, while preserving the underlying codec result separately.
