Hello,
If it is keeping you from running NF1340 because of that message, there should but a button that says "actions" with the download bar. Upon Clicking Actions, there should be a button that says "Run Anyways".
Im pretty sure this varies from browser to browser where the action button is (Correct me if im wrong someone), When I install using google chrome theres usually a bar across the bottom with the download progress and when it is complete it says "actions" in the bottom right part of it.
Hope this helps you out.
