Roon will not update from Version 2.0 build 1368 running on Rhine Z1; it tells me that "There was an error checking for an update," even though it tells me that a new version is ready for download. I have backed up the system and tried to install a fresh version, but I need help to install it.   
After I updated ARC, it will not connect to the older operating system 1368. What can I do to update and reconnect ARC?

Hey @Rbt_Davis,

Welcome to the community! I have moved your thread to the tinkering section, please be aware that this Core is not officially supported by Roon:

> [@Rhein Z1 Roon Server : official or unlicensed? \[—\> unlicensed\]](https://community.roonlabs.com/t/rhein-z1-roon-server-official-or-unlicensed-unlicensed/79492):
>
> This product is currently being distributed in France (and probably elsewhere) at a retail price of 1800€. @danny is this Thunder Data company an official partner ? Can’t see them on the partner list. Looks expensive and with unsubstantiated bla bla as marketing pitch. [http://www.thunder-data.com/z5](http://www.thunder-data.com/z5)

In this case, please reach out to the manufacturer for further details/troubleshooting.
