Hi John, Sounds like whatever CouchDB 1.6.1 left behind is causing you issues. As I wasn't responsible for that installer I'm not sure I can suggest anything other than a full uninstall and reinstall of CouchDB 2.0.0. After uninstalling, be sure to completely delete the left behind C:\CouchDB directory.
The collation driver not appearing likely means that the icu DLLs cannot be found by Erlang. In a working install, you'll find these files at path: C:\CouchDB\bin\icu*.dll There should be 9 files that match this pattern: 2016-06-16 15:57 25,911,296 icudt55.dll 2016-06-16 15:56 1,949,696 icuin55.dll 2016-06-16 15:56 51,200 icuio55.dll 2016-06-16 15:55 257,024 icule55.dll 2016-06-16 15:55 49,664 iculx55.dll 2016-06-16 15:56 61,952 icutest55.dll 2016-06-16 15:56 194,560 icutu55.dll 2016-06-16 15:55 1,376,768 icuuc55.dll Be sure the path to CouchDB has no spaces in it, like the sample above.
