Yes. Routers do not install in any way whatsoever and their clients (the PCs in a network) do not even see the router directly, as the network adapters do that.
Configuring a router is very simple indeed. Run an Ethernet cable between the router and a client - laptop, desktop, does not matter - and open a browser. Type 192.168.2.1 (for Belkin routers) into the address bar and you're in.
