I have a new machine running Windows 7 64bit Home Premium. The installer wouldn't work regardless of Administrator rites or compatability settings. I followed the advise of ConfigFull and copied the whole folder from my old confuser to Program files (x86) and it worked like a dream, even remembering my settings and log on. My guess is that the installer won't work on a 64 bit machine, hence some people have no problems whilst others come up against a brick wall. Anyway, my thanks to ConfigFull.
