I had the same issue on Windows XP SP3.
Issue is I had it installed to a network drive - Z:\. This is because my local C: drive is on a very slow SSD, so writing stuff there takes a while. So I install apps on a network drive.
It appears that this broke the Media Center 14 Service, which wouldn't start - I tried to start it manually and it said it couldn't find the file. I could see the path was pointing to Z:\.. so I figured it wouldnt start a service from a network path.
I uninstalled MC and re-installed to C:\, and now the Remote Wizard works.
