The 'About SketchUp' should look like this: [image: 3kTO_Capture.PNG] for the latest version of v2014...
You should be able to Install it in such a way that will update it to be the latest v2014.
If it's offering a Repair and you choose that route, then can I assume it does not update it to the current version ??
Your ultimate option is to uninstall your out-of-date v2014, as it offers you: and then re-install it cleanly...
It will keep any previous licensing files, custom Plugins, Materials, Components, Styles etc, but you will loose all toolbar statuses, dialog setups etc that are Registry dependent...
