When I tried to install Solarwinds-Orion-NTA-v3.6 on the NPM 10.1 beta I got the following error after installation:
Database configuration failed:
• Exception while configuring plugin NetFlow Traffic Analyzer component NetFlow Database. Method not found: 'Void SolarWinds.NPM.DAL.PollerSchemaManager..ctor()'.
I reran the CW and it listed the NetFlow Traffic Analyzer and ran through it again.
This is one of the post-beta issues we found and should be fixed in a future release. For now, there is a workaround that might help you: take the SolarWinds.NPM.Base.dll file from your existing Orion 10.0 installation, and copy it to ProgramFiles\SolarWinds\Orion\ in the beta installation. Re-run the NTA installation and it should work.
