ad 1) Yeah you right, it's known issue and we have it already in our queue to fix.
Till fix for that will be released you can use this workaround:
Copy file "Netflow-OrionReportWriter.Schema" to "c:\Program Files\Solarwinds\Orion\NetFlowTrafficAnalysis\" folder on machine with web-standalone installation
This file can be copied from station where you installed NTA collector.
Hope this helps you.
That workaround is what I needed. I'm a bit baffled as to why no one from the support team told me to try that. Someone might want to make sure support knows about the workaround, as this has been an issue for me for over a year.
