UnsupportedClassVersionError (Barry and Praveen)

Hi Barry and Praveen. Thanks for your help. I have been out of town for a few days. In case you guys don't see it I bring the topic to the front.
I have done a search on my entire hard disk and I found the java.exe that caused the problem. It is in the C:\WINDOWS\System32. But the problem is I don't know how to remove the path. I can only see the path value

Path=C:\WINDOWS\System32;C:\Sun\AppServer\bin;C:\j2sdk1.4.2_08\bin

when I do set in the command prompt. But I can't see C:\WINDOWS\System32 if I go to the System Properties -> Environment Variables window. I only see C:\Sun\AppServer\bin;C:\j2sdk1.4.2_08\bin. Why is that ? And I don't know why the java.exe file sitting in the C:\WINDOWS\System32 for. Can you guys explain ?

Don't know who Barry (Gaunt?) and Praveen (who?) are, or why you're addressing this to them. Maybe this was moved from some other forum? But in any case, 1) that java.exe is there because some installer put it there, most likely a Java Plug-in installer, and 2) Changes to environment variables affect only programs started after the change, so close your command prompt and open a new one.

Thanks Ernest. This question is a continuation of an earlier thread on
Sep 23rd. It was Barry Gaunt and Praveen Babu answering my question.
My question is that if I do set in the command prompt I can see

Path=C:\WINDOWS\System32;C:\Sun\AppServer\bin;C:\j2sdk1.4.2_08\bin

But I can't see C:\WINDOWS\System32 as path value if I go to the System Properties -> Environment Variables window. I only see C:\Sun\AppServer\bin;C:\j2sdk1.4.2_08\bin. Why is that ? How can I remove
the path value C:\WINDOWS\System32 if I can't see it in the
System Properties -> Environment Variables window. The java.exe file is in this folder.
