Hello all, 

Apologies for the first time question being a support-ish query, but I am very new to all this and a touch miffed with an error.

I have installed WebMatrix, and followed the video "Installing DotNetNuke 6.1.3 with WebMatrix" as far as I was able. I already have SQL Server 2008 Express installed on my local Windows 7 PC.

DotNetNuke appears to be installed no problem, but unfortunately as soon as it loads the web browser with this URL: http://localhost:30817/ (in this case I'm using the latest version of Chrome) I get an error and am unable to complete installation / setup:

Server Error in '/' Application.

Security Exception

Description: The application attempted to perform an operation not allowed by the security policy.  To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file. 

Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

Source Error: 

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Stack Trace: 

[SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.] System.Reflection.Assembly._GetType(String name, Boolean throw , Boolean ignoreCase) +0 System.Reflection.Assembly.GetType(String name, Boolean throw , Boolean ignoreCase) +42 System.Web.UI.Util.GetTypeFromAssemblies(ICollection assemblies, String typeName, Boolean ignoreCase) +145 System.Web.UI.TemplateParser.GetType(String typeName, Boolean ignoreCase, Boolean throw ) +73 System.Web.UI.TemplateParser.ProcessInheritsAttribute(String baseTypeName, String codeFileBaseTypeName, String src, Assembly assembly) +111 System.Web.UI.TemplateParser.PostProcessMainDirectiveAttributes(IDictionary parseData) +279
Version Information: Microsoft .NET Framework Version:2.0.50727.5456; ASP.NET Version:2.0.50727.5456

Would anyone possibly be able to help me resolve this please?

Kind regards.

It's been a while since I used that to install DNN but see if you need to keep it open in order to access the website. That happens in other tools as they dynamically create the port in the URL and closing the application removes the URL.

Thank you Mark, I actually haven't closed anything down during installation - I let it run through all it needed to, then it automatically loads the web browser to "finish installation", at which point I get the above error...

Hi all, just to let you know that I have resolved this issue - it appeared to be something wrong with the location I had set as the default installation directory for the websites. I've changed this to a new folder and it opens the web browser no problem and proceeds to installing the default DNN starter site.
