I've done a clean install of windows on my computer. Unrelated to Lotro. I'm trying to start up Lotro for the first time and does the download check, the screen to select my world comes up. I chose a world. Initializing appears in the window that world select was - and Windows explorer - the file manager one not the internet browser - pops up open to my lord of the rings folder with a gold ring in the very top left corner with the words "Where is the game client executable?" as if it wants me to navagate to where the client executable is??

Does Lotro now need to be actually installed once? Previously I've always just saved an up to date copy of the game on another drive and copied it over and launched it after installing windows.
