Java DK is not getting installed

  1. Jun 20, 2010 #1

    I installed java developers' kit today, but in c:\program files by mistake. I wanted to change it to c:\, so initially I just cut-pasted it. It didn't work, so I uninstalled it (add or remove programs in control panel). However, when I tried to delete the "java" folder in c:\, it said that some file was write-protected and couldn't be deleted.

    I tried to install java DK again, this time mentioning the correct destination, but it wouldn't install. I get an error no. 1721 saying that "there is a problem with this package of windows installer. A program required for this install to complete could not be run" . I am surprised because, earlier, when I had installed java (albeit, at the wrong destination) there was no such error.

    I also tried System Restore, but the folder "java" is still stuck there, and I keep getting error 1721.

    Any help would be appreciated. Thanks in advance.

    Try reinstalling over the old installation (in the same folder exactly). If that works, then formally uninstall that (via Control Panel). Then reboot, and try again.
