DNN - Module installation error
Posted by Andy Williams, Last modified by on 28 August 2006 07:05 AM

I was trying to install a couple of Modules to DNN. The first one I tried was the 'blog' module and it failed, with error,

StartJob Creating files Failure ExceptionSystem.UnauthorizedAccessException: Access to the path 'E:\Domains\domainname.com\wwwroot\DesktopModules\Blog' is denied. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.Directory.InternalCreateDirectory(String fullPath, String path, DirectorySecurity dirSecurity) at System.IO.Directory.CreateDirectory(String path, DirectorySecurity directorySecurity) at DotNetNuke.Modules.Admin.ResourceInstaller.PaDnnInstallerBase.CreateModuleFile(PaFile File, PaFolder Folder) at DotNetNuke.Modules.Admin.ResourceInstaller.PaDnnInstallerBase.CreateFiles(PaFolder Folder) at DotNetNuke.Modules.Admin.ResourceInstaller.PaDnnInstallerBase.Install(PaFolderCollection folders) at DotNetNuke.Modules.Admin.ResourceInstaller.PaInstaller.Install()


Answer: This is caused by a messing up of the default permissions, required for smooth running of DNN. The most common cause is the installation of FrontPage extensions on the same domain, where DNN is installed. FrontPage takes control of the domain, assigning folders & files custom permissions, as per FrontPage setting These permissions are not enough/tend to conflict with the permissions required for smooth running of DotNetNuke.


Please uninstall FrontPage extensions from the domain via HELM and raise a support ticket requesting re-assignment of default permissions to domain.
