ERROR_MRM_NAMED_RESOURCE_NOT_FOUND

ERROR_MRM_NAMED_RESOURCE_NOT_FOUND means the selected resource map exists, but it does not contain the requested logical resource name.

Compare the requested key with the resource names actually emitted into the PRI, including namespace and case-sensitive build inputs where applicable. Missing candidates and a missing logical resource are different failures and require different fixes.

What to check

Inspect the PRI dump for the exact resource name that was indexed.
Check whether the application is querying the correct resource map and package.
Verify that the resource file is included in the project with the correct build action.

makepri dump /if resources.pri /of resources.pri.xml
