    Hi HSabatin,

    Once you install the Application Initialization Module for IIS 7.5 - Release Candidate, it shoudl be available to IIS. However there are no UI elements to configure this module. http://forums.iis.net/t/1176740.aspx 

    This post also references an article to help setup and configure Application Initialization.  http://learn.iis.net/page.aspx/1089/iis-80-application-initialization/

    Please let me know if this helps you.

    Hi HSabatin,

    There is no GUI user interface to configure this feature.  Currently you must configure it using the applicationHost.config at the machine-wide level or using the the web.config files at the site or application level. 

    This article walks through the various settings and how to configure the files:


    In IIS Manager you can use the "Configutation Editor" to verify that Application Initialization was installed and configure a few settings.

    - Open IIS Manager

    - Open Configuration Editor

    - Go to config section "system.webServer/applicationInitialization"

    - Modify settings for Application Initialization

    Hi HSabatin,

    You most likely need to wait for the application to finish initializing on the first load. 

    Are you using the splash page while waiting for the application to initialize? 

    I believe the idea here is to display a static page while your dynamic content pages initialize in the background.

    Hi HSabatin,

    There are two things that need to be set in the applicationHost.config file. The application pool needs to be set to startMode="AlwaysRunning".  And the site needs to be set needs the perloadEnabled="true" attribute set.


      <add name="appinit" autoStart="true" startMode="AlwaysRunning" managedRuntimeVersion="v4.0" />


            <site name="Default Web Site" id="1" serverAutoStart="true">
                <application path="/">
                    <virtualDirectory path="/" physicalPath="%SystemDrive%\inetpub\wwwroot" />
                <application path="/appinit" applicationPool="appinit" preloadEnabled="true">
                    <virtualDirectory path="/" physicalPath="C:\inetpub\wwwroot\appinit" />
