I got the following two errors when I open Sitecore 6.3 website in Visual Studio 4.0:
Error 1 The virtual path '/sitecore/shell/Applications/Analytics/ReportRunner/DateSelector.ascx' maps to another application, which is not allowed.
Error 2 Unknown server tag 'ds:DateSelector'.
I simply install Sitecore 6.3 (website save into c:/inetpub/wwwroot/sitecoresite/website). When I open this site in Visual Studio 4.0, it shows error.
Can any body tell to me how can I open this or what mistake did I make?
