Windows 7 64bit Java problem

Hi
Please can someone help, for a while now i have not been able to run Java programs on my windows 7 64bit machine, i know it has something to do with corrupt or missing registry settings and file associations, but just cant seem to get it to work, i have also made matters worse as before i could run them on one user account but not the other. Now i cant get them to run on either :-(
Please can anyone help??

The error message comes up saying "Could not find the main Class" whenever i double click a jar file.

Also when i download a java file/program the icon is just blank, so windows does not know how to open the file.

I am not that technical so if you could give me step by step instructions and i can try it when i get home tonight.

Thanks Pete
