hey guys i installed jdk1.5 on my pentium 4 machine windows 2000professional edition and then due to some reason i uninstalled it from the system not from the add/remove program but from the installation directory and them when i'm trying to install it again it is showing the message that jdk1.5 is already there in the machine and asking me to remove it from add/remove menu. But i'm not able to delete it from add/remove menu. I already have checked the registry setting but still not able to install it . plzzz help ..thank u...

Not using the 'approved' uninstall process can leave your system in a mess.
I suspect that there is an entry in the Windows Registry that needs to be removed or changed to allow the re-installation to procede.

You can look at the registry with the regedit tool. Careless changes to the registry can criple your system, SO BE CAREFUL!!!

Open the registry with regedit and look at:
HKEY_LOCAL_MACHING\Software\JavaSoft\
There should be several sub levels under that:
Java Development Kit

Use the Registry|Export menuitem to export the JavaSoft entry.

Compare the values in your JavaSoft entry with those on another machine that doesn't have the SDK installed.

The next step is the DANGEROUS one! Change your registry to match the other one. I WOULD NOT recommend doing this, but it may be the only way.

Good Luck.


A little knowledge can be a dangerous thing.

What exactly did you do?
i uninstalled it from the system not from the add/remove program but from the installation directory


What did you check in the registry setting?

Perhaps you can check the Recycle Bin to see if the files are still available. If they are, you can restore it and use the Control Panel to remove them normally (and reinstall if necessary).
