I think I have some Java RTE problems on my Windows machine. So I
tried to uninstall it and then reinstall it, but the Windows Control
Panel/Add or Remove Programs utility fails to uninstall it.

I see that the Registry lists 1.4, 1.4.1, 1.5, 1.5.0_06, 1.6, 1.6_03,
and under that last one MSI.

My C:\Program Files\Java has the following directories jre1.5.0_06,
jre1.6.0_02, & jre1.6.0_03, although the middle one seems to be
missing most of what's in the other two.

When I try running Eclipse, nothing happens. When I try running
JGrasp, it tells me that my JRE is corrupted. I haven't noticed any
other problems.

What are my safe steps from here (or whom should I contact for better

Try to remove it with the control panel then go into C:\Program
Files\Java and delete all the JRE and JDK directories. Download the
latest JDK version, 1.6.0_03 and install it. Remember that on Windows,
XP anyway, you have to set the path to the compiler bin directory. Do
that via Start, Control Panel, Performance and Maintenance, System,
Advanced Tab, Environment Variables button.

Add C:\Program Files\Java\jdk1.6.0_03\bin to either PATH. I prefer the
user PATH but that is just me. Remember that it doesn't effect any
already open DOS windows.

That's it, you should be good to go.
