If you have one version in your comp.. then the req other version won't work and junk.. JRE v2.01 Can we all work together to get rid of Java/Sun plugins forever.. Has to be some other better method outthere.
I am speaking from a developer's perspective, but can't you solve the problem by going to java.com and downloading the latest JRE? It is a simple process. Oh - also - which browser are you using? IE or FireFox?
