I just installed FMS 12.0 v4 on a Windows 2008 R2 with 4 Gigs of Ram and IIS turned on. I ran the FileMaker install and everything has gone smoothly except Instant Web Publishing. The Admin Console shows the IWP is running. However, if I try to run something on it (e.g., http://127.0.0.1/fmi/iwp), nothing comes up and it tries to download an iwp.exe file. It does this both on this Windows machine in Internet Explorer as well as if I run it on a Mac using Safari. What is this iwp.exe? I am more familiar with Apache, but is there something I need to do with IIS to get Instant Web Publishing working? Thanks.
