Notes when installing the connector for the first time
The name of the full installation package for Sitecore 10 is SDL TMS Sitecore Connector10 - Full.zip.
When you install the connector for the first time, the only items that you may already have on your machine are Newtonsoft.Json.dll or System.IO.Compression.dll. If this is the case, when prompted to overwrite either one of these files, select No. Otherwise, the Newtonsoft DLL file for the Sitecore instance will be overwritten, taking down the server. The only solution to this is to revert to the original DLL file.
