    On XP you add and remove programs from the Control Panel by selecting ... "Add or Remove Programs".

    But before you reinstall the jre you should make sure there really is something wrong with it. You haven't posted the contents of the .bat or the (complete) console message so it's really a bit hard to know at this distance whether a reinstallation is justified.

    Begin by writing a small "hello world" type app and launch that from a batch file and see what happens.
