COMADMIN_E_LIB_APP_PROXY_INCOMPATIBLE

COMADMIN_E_LIB_APP_PROXY_INCOMPATIBLE is the failure HRESULT 0x8011044F (signed decimal -2146368433, unsigned decimal 2148598863). Its severity bit is 1, facility is 17 (FACILITY_ITF), and the facility-specific code field is 0x044F.

COM+ application type and proxy compatibility: exact meaning of COMADMIN_E_LIB_APP_PROXY_INCOMPATIBLE

Library-application configuration is incompatible with application-proxy behavior. COM+ deployment detects a package or target combination that mixes in-process library semantics with remote proxy semantics.

AllStat records this condition as “Library applications and application proxies are incompatible”.

Where COMADMIN_E_LIB_APP_PROXY_INCOMPATIBLE occurs

Library applications run in the creator process, server applications own a server process, and application proxies contain client-side remote registration; those roles are not interchangeable. In the specific case of COMADMIN_E_LIB_APP_PROXY_INCOMPATIBLE, record source application type, proxy export/import path, activation setting, and intended client/server boundary.

Evidence to collect before repair

  • Evidence for COMADMIN_E_LIB_APP_PROXY_INCOMPATIBLE should include application Activation/type property, captured before a repair changes state.
  • Collect source server and client roles when diagnosing COMADMIN_E_LIB_APP_PROXY_INCOMPATIBLE; without it the symbolic HRESULT is underdetermined.
  • The COMADMIN_E_LIB_APP_PROXY_INCOMPATIBLE investigation needs proxy package provenance so the exact failing boundary remains reconstructable.
  • For COMADMIN_E_LIB_APP_PROXY_INCOMPATIBLE, preserve RemoteServerName and marshaling metadata; it anchors the failure to the real administration object.

Diagnostic sequence for COMADMIN_E_LIB_APP_PROXY_INCOMPATIBLE

  • At the COMADMIN_E_LIB_APP_PROXY_INCOMPATIBLE boundary, identify the actual server application.
  • The next COMADMIN_E_LIB_APP_PROXY_INCOMPATIBLE diagnostic action is to choose server activation when remote access is required.
  • To isolate COMADMIN_E_LIB_APP_PROXY_INCOMPATIBLE, export a proxy from the server application.
  • For COMADMIN_E_LIB_APP_PROXY_INCOMPATIBLE, remove stale incompatible client registration.
  • At the COMADMIN_E_LIB_APP_PROXY_INCOMPATIBLE boundary, test remote activation with the regenerated proxy.

Difference from nearby COMADMIN results

COMADMIN_E_CAN_NOT_START_APP also recognizes non-server types, but this value identifies the library/proxy combination specifically.

Retry and recovery

Use a server application for remote activation/proxy deployment or keep the library application local.

Practical administration scenario

A team exports registration for a library application and tries to install it as a remote application proxy.
