Running GOG 692 Applets at Home
Starting with Java Run-time Environment (JRE) 7.51, Java applets without certificates will not run under your default Java permission settings. To remedy this, please perform the following steps:
On a Windows 7 PC
Click Start and type ‘Configure Java’ in the Search Programs and Files window. Click on the link for Configure Java. The Java Control Panel will appear.
On a Mac running OS X:
Click the Apple icon on the menu bar at the upper left.
Select System Preferences…
Click the Security tab. Move the Security slider down to Medium and click OK. The applets on my pages should now run.
