ETA (Sept. 2015): Chrome no longer supports the required NPAPI plugin, so please instead use IE11 or Firefox.
Issue: On Google Chrome 42.0.2311.90, the GvNPRT_LivexPlugin_150430 plugin will download and run, but the live view still does not show up.
Solution: 1. Open Chrome and type about:flags in the address bar (or chrome://flags)
2. Locate “Enable NPAPI” and select the Enable option
3. Close the browser and reinstall the plugin
