During the startup process, wrapper is complaining about the dll. Loading native library failed: wrapper.dll Cause: java.lang.UnsatisfiedLinkError: \Wowza Media Server 3.0.2\bin\wrapper.dll: Can’t find dependent libraries. We are running 64-bit JVM on windows 2008 server. Do we need to get 64bit dll? Any advise is truly appreciated. ---

Probably you do not have .NET framework installed. Mentioned here: [https://www.wowza.com/docs/how-to-set-up-and-run-wowza-transcoder-for-live-streaming](https://www.wowza.com/docs/how-to-set-up-and-run-wowza-transcoder-for-live-streaming) ---

Thank you, will check on .NET framework.
