Software Updater

Software updater states that there is an update for Java Runtime environment 7. When I try to update I get the message:

“Error 1500. Another installation is in progress. You must complete that installation before continuing this one.”
As I have only started one installation I am puzzled. Does anyone have any ideas how to install the latest version of the Java Runtime environment please?

Thanks

try uninstall first…then install again

Thanks for your quick reply - much appreciated.

Apologies for my ignorance but how do I do that?

Controlpanel > ad/remove programs

Thanks for your help - all updated now.
