Thanks Tachibana
Seventh time lucky
I've installed into C:\Program Files (x86)\Steam\SteamApps\common\Company of Heroes
and separately (with previous deleted) C:\Program Files (x86)\Steam\SteamApps\common\Company of Heroes Relaunch
Both times I'm a dumbass as it isn't in the right folder. I might be dull but can't find any notes on this.
I am very much a dumb ass. I've sorted it. I had to copy and paste the EIRR folder contents into main COH folder
