Hi, I have the same issue with trying to unistall Java. Originally, I had an outdated version and attempted to update. The update gave me an error -- The feature you are trying to use is on a network resource that is unavailable. Enter an alternate path to a folder containing the installation package "jre1.7.0_21-c.msi" Then an error msg pops up that says installation source is unavailable.
I've already uninstalled the outdated Java, but this update won't allow me to uninstall from the control panel. It keeps giving me an error. Apparently, the destination folder is not on my computer, but I don't know how! Can you please help me?
