NW Troubleshooting


Issues Opening NW Files

NW.js Removed

Double-clicking your NW file prompts the message "%%os%% Can't Open NW File". Customarily, this means that NW.js is not installed on %%os%%. The OS won't know what to do with your NW file, so double-clicking to load the file doesn't work.


Tip: When you have another program installed that you know will open your NW, you can select it from the other programs listed (see "Show Apps").


Outdated NW.js

In some cases, you might have a newer (or older) version of a Node-Webkit App Package file that is unsupported by your installed application version. Visit the GitHub, Inc. website to download (or purchase) the latest version of NW.js. This problem is most common when you have an older version of the software application, and your file was created by a newer version that it cannot recognize.


Tip: Sometimes you can get a clue about the version of NW file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).


Summary: Not having the right NW.js version on your computer can cause problems opening NW files.


Associated Difficulties Loading NW Files

Errors opening Node-Webkit App Package files can still occur even with the latest NW.js software installed on your computer. There can be external issues inside of %%os%% that are causing these errors when opening NWs. Other contributing causes:

  • Invalid NW file references in the Windows Registry (the "phonebook" of the Windows Operating System)
  • Mistaken removal of the Windows registry NW description
  • Partial installation of NW.js that did not fully complete
  • Your NW file is corrupted (issues with your Node-Webkit App Package file itself)
  • NW file integrity has been compromised by malware
  • Hardware associated with NW has outdated drivers
  • Insufficient system resources to successfully open Node-Webkit App Package files
