Hey: I have this problem every time I set things up in IIS w/ rails. Here’s my checklist: 1. Is your app mounted to the root of your server? 2. Where’s your ISAPI.FCGI.DLL file located? Your IIS Guest user should have READ access to the file. 3. What URL rewriter are you using 4. What rule do you use for your rewriting? 5. Did you set the required variables for .fcgi in the registry? 6. What are those variables? 5a. AppPath = c:\ruby\bin\rubyw.exe 5b. Args = c:\your\railsapp\public\dispatch.fcgi 5c. BindPath = rails-fcgi 7. Did you set up the app mapping in your site root to point .fcgi to isapi\_fcgi 8. most importantly, did you allow fcgi in the “web service extensions”? Finally, did you see this page? [http://rubyforiis.sosukodo.org/](http://rubyforiis.sosukodo.org/) (RubyForIIS) If you did, try installing Ruby For Apache [http://rubyforge.org/projects/rubyforapache/](http://rubyforge.org/projects/rubyforapache/) because sometimes you need to do that a few times. (don’t know why, but once it’s working, it does stay that way. If there’s any way I can be of assistance, let me know! ---

You should try running Ruby for IIS (dont have link, but its on the wiki). I got that error as well when I tried to install Ruby for Apache, but didn’t have apache installed. I may have seen on my XP laptop too, but can’t remember. -Nick ---

Stephen, I think that RubyForApache needs to copy a version of “msvcp71.dll” to your system32 folder. It needs it to recompile fastcgi or something else. The problem (at least on Windows XP, on Win200 I didn’t had this problem) is that you already have a copy of “msvcp71.dll” in your system32 folder. What I did was to rename my original copy to “msvcp71\_original.dll” or something , let the RubyFoApache installer do it’s thing and then rename the new one to “msvcp71\_rubyforapache.dll” and put back my original. I think this dll is the c++ compiler from VisualStudio. Or is needed by the compiler … whatever. Hope this helps. Marius P. [http://mapopescu.blogsome.com](http://mapopescu.blogsome.com)
