"The specified module could not be found"

[vincenthawke]

Windows 10, node version v10.15.3, npcap version 0.995.

I was unable to run a simple code example:

const Cap = require('cap').Cap;
console.dir(Cap.deviceList());

It gives an error:

PS C:\Users\Home1\Desktop\nodecap> node index
internal/modules/cjs/loader.js:730
  return process.dlopen(module, path.toNamespacedPath(filename));
                 ^

Are you sure the addon was compiled successfully when you installed it?

I deleted all and tried again. Here is the installation console output:

PS C:\Users\Home1\Desktop\nodecap> npm install cap

> cap@0.2.0 install C:\Users\Home1\Desktop\nodecap\node_modules\cap
> node-gyp rebuild

Not sure if this is 100% without problems, it seems to be but I don't know.

That looks fine. Did you also make sure to check the 'winpcap compatibility' option when you installed npcap?

That I did not but I remember seeing this last checkbox in wireshark installation process. Let me try reinstalling it...

[vincenthawke]

Works now:) Winpcap compatibility checkbox fixed it: http://prntscr.com/om78fg Thank you!
