ERROR_MRM_INVALID_PRI_FILE

ERROR_MRM_INVALID_PRI_FILE means the resource-management runtime could not treat the specified file as a valid Package Resource Index. A PRI is data-only and contains the resource map and its candidates.

What to check

  • Run a PRI dump to determine whether the file can be read as an index.
  • Verify that the file belongs to the same package build and was not truncated or replaced during deployment.
  • Rebuild the PRI from the project resources if the dump or build logs show an indexing problem.
makepri dump /if resources.pri /of resources.pri.xml
