The Soft-eLicenser’s file access permissions should get fixed upon re-installation of the eLC runtime (latest eLC installer can be downloaded here).
If this doesn’t help, and you’re sure that no important licenses exist on that Soft-eLicenser, you might as well delete the Soft-eLicenser itself to get rid of these warnings; on Windows, it is located at
%programdata%\Syncrosoft\SeLicenser.sel
