I'm having problems uninstalling jdk 1.4.0....
I tried reinstall JDK 1.4.0 using Windows' Add/Remove Programs..... But then when I installed the it, the JDK.14.0 item in the Programs list is still there.. and also upon, cheking the directories in Windows Explorer.. the directory for the JDK1.4.0 is still there... SO i deleted the directory myself...
And then when i was about to reinstall JDK1.4.1, it generates a message.. prompting me to delete the previously installed version of JDK1.4.1 before I can start installing again... If the add/remove doesn't how do i remove it manually?
where can i find the entries and files needed to properly remove it manually?
Help please... don't know what to do...

it's alright, the gun isn't loaded... - hey

Try doing the following, this is what I do to clean my J2SE 1.4.0_01 installation. On similar lines you can do it for jdk1.4
Go to Control Panel; select Java Plug-in. Click on the Browsers tab. Uncheck both IE and Netscape6.
Remove the directory in which you placed the J2SE JRE. For example, remove C:/Program Files/Java/j2re1.4.0_01 if you have not removed.
Remove the following files from the Microsoft Windows System Directory:
On Microsoft Windows NT, 2000, and XP:

On Microsoft Windows 98 and ME:


Remove the following Registry Keys after running regedit.exe:
HKEY_LOCALE_MACHINE/software/Javasoft/Java Runtime Environment/1.4.0_01
Delete the following key if it exists-
HKEY_LOCALE_MACHINE/software/microsoft/windows/currentversion/uninstall/7C F31609-270B-11D6-9445-000102308676
I agree. Here's the link:
