I\'ve setup a new .net 2.0 website on IIS 7 under Win Server 2k8 and when browsing to a page it gives me a 404.17 error, claiming that the file (default.aspx in this case) a
%windir%\Microsoft.NET\Framework64\v2.0.50727\aspnet_regiis.exe -i
worked for me after getting "An attempt was made to load a program with an incorrect format ..." with the 32 framework
maybe ill save u one more sec googling
