Open the ASP.NETWebAdminFiles website using any Visual Studio

Inside your wesbite project, browse to the C# file

ASP.NETWebAdminFilesApp_CodeWebAdminPage.cs

Go to Line 989

Comment the line out // string appId = StringUtil.GetNonRandomizedHashCode...

Add a new line string appId = "1"

Save the website, Unload it from Visual Studio

Run IIS Express in CMD
