Could not load file or assembly 'Newtonsoft.Json, Version=10.0.0.0

I am new to Octopus and am trying to sort out my first Tentacle Listener. I downloaded the suggested version at the time which was 5.0.1-x64 and am installing it on a Windows Server 2016 10.0.14393.

Immediately after configuring the listener, I got the below error:
postConfigError

After restarting I got a similar error. A colleague suggested patching .NetFramework so I installed 4.7.2 but got the same issue.
postRestartError

Please assist in resolving the issue

Hi @lukelindner,

Thanks for getting in touch! It looks like we had a problem with Tentacle version 5.0.1 and have resolved this issue in Tentacle version 5.0.2. If you download the latest version and try the installation again, this should work for you.

Let me know if you get stuck here or have any further questions.

Best regards,
Daniel

Thanks. This fixed it :slight_smile:
