Cannot uninstall Java JRE 1.7 32bits

For some reason my firefox browser stopped detecting java and now I can't run anything with java on it because it says that it's not installed, so I went to add/remove programs and tried to uninstall java but it just won't get removed.

So when I try to uninstall it (Java(TM) 7 Update 5) a little window appears with a progress bar, after it completes it disappears but Java is still there..

this is the window that appears: http://rcupload.com/images/HLUwZ.png

Here's what I tried to do:

1) Use CCleaner to uninstall it: - I choose the program, press uninstall and it disappears, but when I refresh the list it will still be there. I also tried using the "remove entry" button in CCleaner and i just get a message saying "cannot delete msi installer'.

2) I tried using JavaRA: - I ran it as administrator, clicked "remove older versions", and I got the message that Java JDK 1.7 was uninstalled and all the files, but now I see that there is no folder for it at "C:\program files (x86)\Java\" (there was one inside before, called something like jre-7) and the icon in the installed programs appears like a white box instead of looking the like the java logo.

3) I tried downloading java and installing it: - I run it, it downloads and it gets to a screen where it asks me if I want to install a toolbar, I click next and I get this message: http://rcupload.com/images/xiCIu.png

-- Resumed: I need to get rid of Java(TM) 7 Update 5 but the uninstaller seems not to work and files are missing.

Any help will be appreciated!

Thanks.

I was having the same exact problem, and solved it using Microsoft Fix it tool, here: http://support.microsoft.com/mats/program_install_and_uninstall

Finally, a Microsoft troubleshooter that actually works !

I haven't experienced this before my self. Here's my guess. One may say this is a 'harsh' way to remove and cause system in-stability. But I don't see any other way with the given details.

Please don't continue if you don't understand every step. This is almost what the un-installer does behind the scenes. You will have to do them manually.

  • First Un-install Firefox.
    • It doesn't detect the Java version installed for some reason where the Java installer does. you'll have to re-install it later when everything is fine.
  • Delete (i mean, backup) your JRE folder in 'Program Files'
  • Open regedit, and find the key for Java Runtime under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall and delete (export it first, just in case) the key. (You'll have to go through each key and see the DisplayName for them.)
    • This will remove the entry in Add/Remove programs and Windows will think there's no Java.
  • Remove Java path from your System's Environment variables.
    • This will cause some apps that check for Java to decide that there's no Java installed.
  • Run the un installer again (if it's still visible in Add/Remove Programs).
    • If Windows still has the reference to the uninstaller, this will cause it to update it self and remove any references because there's no registry entry, and no program files.
  • Reboot the machine.
    • This will flush any waiting changes, unregister stuff .etc.

Try installing Java again. (Installer should not detect that there's Java installed, because there's no Environment variables set, and no registry entries.)

Please try this at your own risk. This may cause issues in your system.

You may get a better answer if posted on superuser site.
