Java SE (Java Platform, Standard Edition)

I have a strange problem with my system. If I have a jar or an applet running, then try to launch a second jar or applet, I get an error stating:

Java Platform SE binary has stopped working

My system is a MACbook Pro running Windows 7 64-bit via bootcamp (yes, I'm booting into Windows). I have both java 32-bit and java 64-bit installed on my system. The executables are located in all the correct paths (I think) C:\Program Files, C:\Program Files (x86), and C:\Windows\System32. I've uninstalled and reinstalled all java versions multiple times and have tried executing the installer as the Admin (I have full admin rights). I also tried disabling the Symantec Endpoint protection during installation. A few other users in my company are also using the exact same system set up as I am; however, they are not having this problem. We are releasing a Netbeans based development tool to our customers very soon (it's out in Beta form now), so I really need to get this issue resolved. Does anyone have an idea on how to fix this?

Thank you!!
