The client machines needs to run Windows 7 or later but we recommend Windows 10 and a full installation of Microsoft .NET framework 4.6.1.
The clients can run on a Terminal server or a Citrix server. Client software needs to be installed on each client machine.
The clients need to have http 1.1 access to port 80 (or other port depending on what port is configured on the server) on the server and access to a share on the same server (Aiolos folder shared is needed by the legacy parts, not only for Aiolos Forecast Studio).
Note! One factor you may want to consider is that Windows 7 Home Premium can't join a domain, so businesses will want to look at a higher-level version, else there can be problem to connect to Aiolos Forecast Studio.

If the client is a member of another domain than the server is connected to you have to setup a trust between those two domains. You may also have to create an account with the same name in both domains.
