It's definitely a Java error,
I would try the following
Access your add/remove programs and remove ALL older version of Java and updates
You will know which ones they are, the coffee icon will be beside them
Reboot the computer afterwards
Back in Windows
Access the following link and save the latest Java installer to your desktop
Sun JavaClick on Download under
Java Runtime Environment (JRE) 5.0 Update 8Accept the License Agreement
Select "Windows Offline Installation, Multi-language".
Save the installer to desktop
and then double click to install, follow the prompts
Once installed you can delete the installer
