Custom Widget error 404

[RickEhlin__Jr]

I am trying to add a PrintPlus Widget to our WebApp and when trying to Register the custom widget I get the following error.  I'm pretty green when it comes to things like this so any help is appreciated.  Thank you

Rick,

  Are you trying to load the widget in on premise Portal? What version? Or if WAB Dev what version?

I figured it out....Thanks for the reply back though.  You'll probably be hearing from me as I'm just getting into custom widgets.

I'm trying to load it in an on premise Portal. 10.6.  I simply copied the PrintPlus widget folder to my server.  I think I need to put it in my

inetpub->wwroot folder?
