Answer 1

We needed to install ASP.NET 3.5 and 4.5, ISAPI Extensions, ISAPI Filters and Server Side Includes, in the Windows Features menu under IIS Development Features.

Alternatively, do with the command line DISM:

Dism /online /enable-feature /featurename:NetFx3 /All /Source:WindowsInstallers\Win8\sxs /LimitAccess
Dism /online /enable-feature /featurename:NetFx4 /All /Source:WindowsInstallers\Win8\sxs /LimitAccess
Dism /online /enable-feature /featurename:IIS-ISAPIExtensions /All /Source:WindowsInstallers\Win8\sxs /LimitAccess
Dism /online /enable-feature /featurename:IIS-ISAPIFilter /All /Source:WindowsInstallers\Win8\sxs /LimitAccess
Dism /online /enable-feature /featurename:IIS-ServerSideIncludes /All /Source:WindowsInstallers\Win8\sxs /LimitAccess

Always try "Revert to Parent" in Handler Mappings first.

I was getting 404.17 when trying to run ASP.NET 4.0 in IIS 7.5. I tried all of the above and eventually got the correct Handler Mappings manually set up and the error went away.

Then, on yet another website with the same error, I tried "Revert to Parent" in Handler Mappings and it added 6 *.aspx mappings and everything worked perfectly.

Obviously, you'd have to have the parent configured properly (from the install or otherwise), but this is definitely the first step everyone should take since it is so easy.

For me it worked by doing the following

Install ASP.NET

cd %windir%\Microsoft.NET\Framework64/v4.0.30319
aspnet_regiis.exe -i

• Next Go to IIS Manager and click on the server (root) node.
• In features view, IIS section, open "ISAPI & CGI Restrictions"
• Right-click the ASP.NET 4 restriction column and right-click to Allow

Hope it works for you..

Answer 6

Only one way to solve this problem...

First Installed Windows7 Then Install IIS 7 with all features

And then installed Visual Studio 2008 / 2010

I work on visual studio 2008 and 2010 but I never seen this error before.

I can also try on my friend's PC. And also I solve this error.
