I ended up (with Owen being a bigger help, than non-existent support mind you) uninstalling completely, re-installing from disk and then applying patch in safe-mode. The second time it finally took (I cheered once I hit 50%), but I don't think I was applying the patch in safe-mode after the re-install the first time.
So uninstall completely, re-install but don't patch, then go to safe-mode and start patch. I had done a chkdsk as part of the first failed re-install, who knows if that helped.
Tried that. Doesn't work for me.
