1.
Because of problems with my Java application, I'm trying to uninstall Java(TM) 6 Update 23 but i get that error message instead.
I have tried Praseetha's solutions (both methods) in this thread
http://social.answers.microsoft.com/forums/en-us/vistarepair/thread/C5CF205F-85A8-4FFF-A3C2-FB9FA1E99C8E
but the problem persists.
2.
I am uninstalling my Java programs (Jave 6 update 3 and Java 6 update 21) because I am unable to open the Java control panel.
Also, when i try to verify my Java version at the Java website, the browser (both Firefox and Safari) crashes.
Prior to this problem, i installed Java 6 update 22.
Even though it says the installation is complete, i can't find the version on my computer.
Looking forward to hearing from you.
Cheers.
