How do I downgrade to a specific update of Java version 6?

Question

I am used MBA Mountain Lion OSX.
I am trying to use Business Objects through the web and unfortunately Java 7 is not compatible. I was able to downgrade to Java 6u65 (Java 1.6.0_65)  but I really need update 45 to get Business Objects to work. Can anyone help me with the terminal code and/or a download that will allow me to pull out Java version 6u45? (Java 1.6.0_45)?
I've been on here trying several other's codes and it says permission denied or "unable to find any JVM versions matching 1.6.0_45"
Could that mean I don't have version 6u45 available to me period?

Just wanted to post the answer in case others have the same issue. I had to remove ALL java related files in order to install an earlier version and there was ONE transient file that I couldn't find and this code worked
