Application blocked by security settings error on client' Windows8 OS

Question

We are facing this issue on our clients machine.

Our project uses a third party java applet to open the files in respective softwares. On windows7 we don have any issue but we have issue on windows8 OS

our project is working fine in IE10 and FF browsers. of windows8 this error is thrown only in chrome.

but when we execute same third party demo site which uses this same java applet to open the files in respective softwares, that is working fine in all browsers without making any changes in settings.

I have read many replies from different ppl that we need to changes the client java secutiry settings. But how can we ask all our clients to make this setting so this is not a proper solution for our problem. Please see the image below

"Your security system have blocked an application with expired or not yet valid certificate from running"
