I have tried updating java about 7 times now, and every time after I update I try running Minecraft, and I get an error... \
"This application requires a Java RunTime Environment 1.6.0" I just don't know what to do now...
I am on Windows 64 bit.
Uninstall all versions of Java (JRE).
Restart the computer.
Install the latest versions of both 32-bit and 64-bit JRE 6 and JRE 7. You can have both, yes.
