I recently uninstalled an old version of JRE and JDK, then attempted to install the current version of both. However, the installation failed with the error message "Error 25099. Unzipping core files failed." The help page for the message says it is caused by a failed uninstallation that leaves jqs.exe (Java Quick Start) running. But a check of Task Manager doesn't show jqs.exe as a currently running process. Anyone recognize this problem and know how to complete the new installation? Any help will be greatly appreciated!
Having looked at the link fujisan sakura supplied, I think you might have to delete the "Java" folder from Program Files before you try installing the next upgrade. At least I think so; the discussion on the other website was very confusing.
