Hi

I am trying to a clean install on a server, but haven't used dotnetnuke before, and to make matters worse the I have a new web host doesn't offer any support for the product. When I attempt to access the installation directory I recieve the following error (its a long one):

System.Security.SecurityException: Request for ConfigurationPermission failed while attempting to access configuration section 'system.web/deployment'. To allow all callers to access the data for this section, set section attribute 'requirePermission' equal 'false' in the configuration file where this section is declared. ---> System.Security.SecurityException: Request for the permission of type 'System.Configuration.ConfigurationPermission, System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' failed. at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet) at System.Security.CodeAccessPermission.Demand() at System.Configuration.BaseConfigurationRecord.CheckPermissionAllowed(String configKey, Boolean requirePermission, Boolean isTrustedWithoutAptca) The action that failed was: Demand The type of the first permission that failed was: System.Configuration.ConfigurationPermission The first permission that failed was: The demand was for: The granted set of the failing assembly was: The assembly or AppDomain that failed was: System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 The method that caused the failure was: Boolean GetRetailFromConfig() The Zone of the assembly that failed was: MyComputer The Url of the assembly that failed was: file:///E:/web/primordi/portal/bin/system.web.extensions.DLL --- End of inner exception stack trace --- at System.Configuration.BaseConfigurationRecord.CheckPermissionAllowed(String configKey, Boolean requirePermission, Boolean isTrustedWithoutAptca) at System.Configuration.BaseConfigurationRecord.GetSectionRecursive(String configKey, Boolean getLkg, Boolean checkPermission, Boolean getRuntimeObject, Boolean requestIsHere, Object& result, Object& resultRuntimeObject) at System.Configuration.BaseConfigurationRecord.GetSection(String configKey, Boolean getLkg, Boolean checkPermission) at System.Configuration.BaseConfigurationRecord.GetSection(String configKey) at System.Web.HttpContext.GetSection(String sectionName) at System.Web.Configuration.HttpConfigurationSystem.GetSection(String sectionName) at System.Web.Configuration.WebConfigurationManager.GetSection(String sectionName) at System.Web.UI.DeploymentSectionCache.GetRetailFromConfig() at System.Web.UI.DeploymentSectionCache.get_Retail() at System.Web.UI.ScriptReference.IsDebuggingEnabled(ScriptManager scriptManager) at System.Web.UI.ScriptReference.ShouldUseDebugScript(String releaseName, Assembly assembly, ScriptManager scriptManager) at System.Web.UI.ScriptReference.GetResourceName(String releaseName, Assembly assembly, ScriptManager scriptManager) at System.Web.UI.ScriptReference.GetUrlFromName(ScriptManager scriptManager, IControl scriptManagerControl, Boolean zip) at System.Web.UI.ScriptReference.GetUrl(ScriptManager scriptManager, IControl scriptManagerControl, Boolean zip) at System.Web.UI.ScriptManager.RegisterScripts() at System.Web.UI.ScriptManager.OnPagePreRenderComplete(Object sender, EventArgs e) at System.Web.UI.Page.OnPreRenderComplete(EventArgs e) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) The Zone of the assembly that failed was: MyComputer

The config file appears to have the setting mentioned set to 'false'...any suggestions on what the problem is with the installation?

 Hi,

i had the same issue while trying to install DNN 5.1.4.

What i did, is deleting the virtual directory in IIS management console, and re-creating it manually with alias DotNetNuke_Communit. I made sure the ASP.Net version for this new virtual directory was 2.0. I also checked in Visual Studio that the target framework for the website project was 2.0. And then from Visual Studio i launched the website and it works.

Hope that helps.
