Windows is a really bad server platform, especially with R (no fork, no parallel connections, no unix sockets ...). The standard configuration in FastRWeb assumes a unix server (the more common case) and it really consists of install.packages() and then copying Rcgi from the cgi-bin directory of the installed FastRWeb package to your web server's cgi-bin and starting Rserve (via /var/FastRWeb/code/start). Alternatively, you can use the PHP client from Rserve instead of CGI. If you really want to use Windows, I have fixed the Windows build so it should work, but you'll have to configure it by hand -- but as I said, I strongly discourage the use of Windows for any R-related server activities - there are too many security implications and it's far less efficient.
