"IIS is not installed correctly on this server (AppCreate)"
Error Message:

Details:
FogBugz Setup is trying to call the AppCreate function in your web server, which is a standard feature of IIS that allows automated web application setup as opposed to manual web application setup. This step creates the FogBugz website as an application in IIS. IIS in your OS does not support this function. Windows 2000 Pro has been known to not support this function, and NT 4 definitely does not, although it may be possible to download and install the necessary components from Microsoft.
Solution:
We do not recommend that you attempt to download and install support for the AppCreate function missing in your version of IIS. Simply run setup from the command line with the following argument:
/ignoreiiserror
This will allow FogBugz Setup to continue even if it can't set up a virtual directory in IIS. (This requires FogBugz Setup 3.0.5 or later.) You will need to create a virtual directory manually and map it to the FogBugz\website directory, follow the steps under the IIS Settings header in this article.
