You probably called: DownloadManager.register() from the render process.
Please refer to the Examples section in the Readme.

The same error happens for me, And i am calling DownloadManager.register() in the main process.

When i checked the code i noticed that you are using require('electron').app which i think it isn't available in older version of electron (v6 in my case), it would be good to replace that with require('electron').remote.app which is available in every version of electron
