Adobe Flash Player has stopped potentially unsafe operation

Recently I did a training with materials offline using Adobe Flash.

Sources are usually in a compressed file or a CD/DVD drive, and when I ran the starting web page using Microsoft Internet Explorer I’ve received the following error message:

Adobe Flash Player Security

Adobe Flash Player has stopped a potentially unsafe operation.

The following local application on your computer or network:
is trying to communicate with this Internet-enabled location:

Adobe Flash Player has stopped potentially unsafe operation


  1. This error message appeared only using Microsoft Internet Explorer and NOT with Google Chrome.
  2. Unfortunately clicking the button Settings the error message disappears without show any configuration screen and to receive again the error I have to close the browser and re-open it.

As the error message itself is saying, Adobe Flash player stopped the operation because a local file wants to communicate with an “Internet-enabled location” that in our case is local but it could be on internet and for this reason dangerous (“unsafe operation”).
