Safe next steps
- For 15122 (ERROR_MRM_UNSUPPORTED_DIRECTORY_TYPE), identify the resource file, PRI package or merge/load operation that reported the code.
- Check the exact resource format and build tool documentation for the application version; a store reset or PC driver change is not a general fix.
- If you do not develop the app, give the publisher the code and operation instead of editing package files manually.
After one step, repeat the original operation and record whether this same code returns. A different code needs a fresh interpretation.
