Unable to encrypt

[Jason Suttles]

I get this error when running an nwjs (chromium-based) application as a Windows service. It seems to cause a crash which doesn't fully kill the application.

[9416:3580:1218/103717.913:ERROR:app_bound_encryption_provider_win.cc(81)] Unable to encrypt key. Result: Class not registered (0x80040154) GetLastError: 31
Any insight would be very helpful.

It appears nwjs is returning true to IsSystemInstall() but this does not seem like a normal system-level install, as it sounds like the service has not been installed. nwjs should create a InstallMode different from Chromium and put that in e.g. `chrome/install_static/chromium_install_modes.cc` or similar location, and signal that system level is not supported by flipping `.supports_system_level` to `false`.

This ERROR should not be causing a crash though, it's just failing to initialize app-bound encryption. Your crash is likely coming from somewhere else.

Perhaps you could consider running nwjs under a debugger and seeing where it crashes? There's some handy hints on doing this here -> https://www.chromium.org/developers/how-tos/debugging-on-windows/

Thanks for the investigation. Is there anything else in the area that might help? This is the only log that seems to happen at the same time and does not occur independently of this "crash". 

Is this in any way related to localStorage?

Would this possibly be related to some kind of lack of resource error?
