Thanks. I'd found a setup version and installed it. The validator registered everything as installed.
And then I was poking around in the files and I realised my embarressing mistake. I had two installs of SH5 from when I switched computers, one on the F drive where I was installing mods and one on C which was in the registry and Uplay was launching.
I had everything installed correctly, it was just in the right place on the wrong drive the whole time.
Thanks for the help
