In order to setup an IIS 5 uniGUI web application, it is necessary to start creating a new Virtual Directory.
Note: You can add a new Virtual Directory to either the "Default Web Site" or to any other existing "Web Site".
Select an alias for new virtual Directory.
Now assign a folder to the newly created alias.
The next step is to assign the necessary permissions to the virtual directory. Execute permission is required.
After creating a new virtual directory, you are ready to deploy your uniGUI server.Copy your ISAPI module and other required files to the virtual directory. You must be certain that ISS built-in users IUSR_<ComputerName> and IWAM_<ComputerName> have enough rights to access your virtual directory and other folders that may be accessed during the web application execution.
For example, if your ISAPI apps are under folder C:\WebApps then you must give full access to that folder.
Your web application can be loaded by browsing to this URL: http://localhost/<virtualdirectory>/<modulename>.dll
