Your DotNetNuke installation appears to have a security settings problem (most likely permissions). DotNetNuke has extensive file upload capabilities for content, modules, and skins. These features require custom security settings so that the application is able to create and remove files in your website.

Using Windows Explorer, browse to the root folder of the website ( C:\DotNetNuke by default ). Right-click the folder and select Sharing and Security from the popup menu ( please note that if you are using Windows XP you may need to Disable Simple File Sharing before these options are displayed ). Select the Security tab. Add the appropriate User Account and set the Permissions.
