I am trying to do to a new install on a shared host. I get the following error when I navigate to my web site in order to start the installation:

System.UnauthorizedAccessException: Access to the path 'E:\Web\f\fpcoinner\web.config' is denied. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, FileOptions options, String msgPath, Boolean bFromProxy) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share) at System.Xml.XmlDOMTextWriter..ctor(String filename, Encoding encoding) at System.Xml.XmlDocument.Save(String filename) at DotNetNuke.Web.Client.ClientResourceManagement.ClientResourceManager.AddConfiguration() at DotNetNuke.Services.Install.InstallWizard.OnLoad(EventArgs e) at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) 

The server is a 2008R2 with IIS 7.0. I asked the tech support to give full control to the IIS  APPPOOL user for my site, but he is telling me that their is no such user.  So I guess it's because it's IIS 7,0 so he gave full control to the Network Service user but still...

Any advice?

Thanks,
Eric

Thanks for your reply Ken,
The tech support is telling me that they cannot give full control to the user IIS_IUSRS on my root, is their a way around this?

Thanks,
Eric

It seems that the permission Modify; Read/Execute; List folder contents; Read; Write on the root folder of my site cause a breach in the security, and for this reason my hosting provider do not allow such permissions. Is their an other way to process with the install?

Would editing manually the web.config solve the problem?

What are the reasons behind having IIS_IUSRS with such permission?

Can we have DNN working without it and if so what are the consequences?

Thanks again for your help,
Eric
