Started this program and go to the « Security » tab (fig. 6).

You need to set security level on « High », as « Very High » does not allow applets to run. What we will do now it to click on the Edit site list… button then on the Add button to add the website https://i-concrete.ch to the list of sites authorized to run potentially less secure applets (fig. 7). Do not forget the s, or it will not work.

Once this is done, press OK to finish. You can now freely run applets from the i-concrete web site. Well, you will still get a message asking if you really want to run it, which you can confirm!

Do not worry, the applets of the i-concrete website are completely innocuous, as they were written following the basic philosophy of Java applets, which makes no use of locally stored files or resources. This is why they are perfectly secure for you and authorizing i-concrete applets to run on your computer presents no security risk to you.

What comes next?

It is clear that the situation is not going to improve, and it is quite possible that additional requirements will be imposed on us in the future. We will do our best to enhance the security of the applets and enable their execution in a simpler manner, but in the meantime, the solution proposed in these few pages is functional.
