Presently, only few web browsers still support Java, e.g. IE11. Besides, Java blocks an applet by default unless it is distributed with a code-signing certificate bought from a trusted third-party vendor, or its URL is added in the Exception Site List in the Java Control Panel settings. We do not buy code-signing certificates for our applets. However, you may download our "Executable Jar Files" and run them normally as independent programs.
