I have the same problem. I've only seen this happen on Vista too. I'm guessing you have that?
I'm not completely sure, but this is what I believe. I think the path isn't correct in the run batch file, so you need to change it. Steps:
-Right click the run batch file, and select 'edit'.
-It'll show up in Notepad form. Delete the current java path.
-Find your JDK folder and enter the bin folder. [Start>Computer>Partition_1 (C: )>Program Files (x86)Java>JDK (Your version)>Bin]
-Copy the path to the bin folder.
-Paste it where the old path was on the notepad.
-Save it.
It's occasionally worked for me, I don't know if it'll solve your problem though. Again, I have the same issues. I'll check up on this thread so maybe I can get some answers too.
