I am getting a cannot open jar java virtual machine error! I downloaded the new version of java and I have windows xp Os. Can anyone help?

Make sure you un-install all other versions of Java and load the latest 32bit (x86) version.
Maybe a conflict or a corrupt download.
At a command prompt type java -version to make sure your installation works.

How about at launch checking the JVM bit count/version/etc and if not ok, bring up a window giving some instructions rather than trying to load 32 bit deps and failing outright.


I had a poke around and it doesn't look as though it's possible to do better than this without including a JRE with the installer (which is allowed, btw).

Even with the wrong bit version RR will start, so we could do a version check & warning. The RR Logger is the only portion that I know of that "requires" the 32bit version as the supporting libraries do not have 64bit Java support in them.
Sure we could include the JRE. I see with Java 1.7 JDK that might be a requirement to ensure that the source compiles against the minimum required JRE version (1.6). Something to look at one of these days.

It seems the OP problem is not with RR specifically.
