Yesterday i dug up an old sitecore project. when everything was installed and downloaded i tried to login at the sitecore admin. it kept on giving following error: “Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration>\<system.web>\<httpModules> section in the application configuration”. Nice error he The Sitecore version is 6.1 and it is not really compatible with the “integrated” mode of IIS 7.0. IIS 6.0 uses classic mode so we change the application pool setting to “Classic” mode. but that’s not all, then you need to be sure you are using the correct DLL’s for the system. if you are having a x64 machine you will need to find following DLL’s for x64: dtsearchNetApi2 and System.Data.SQLite. and that fixes the problem. enjoy
