On Windows, Arc is available as a desktop application or as a server. To install Arc as a server, the instructions can be found here. Arc Desktop and Arc Server have the same features except that it is easier to use multiple windows with Arc Desktop.

Some features will work with TM1 10.2.2 but a number of important APIs are only present in TM1 11+, for this reason we can’t help you if you are on TM1 10.2.2 or earlier.

The TM1 REST API is required for Arc to work, it can be enabled by setting the HTTPPortNumber parameter in the tm1s.cfg file, i.e. HTTPPortNumber=8111. See: code.cubewise.com/blog/enabling-the-tm1-rest-api

Arc Desktop shouldn’t be installed on the server. If there are multiple developers in your team, we recommend to install Arc Server on the TM1 server. So all developers will use the same version and you will only have to do one upgrade.
