Solution 1

IIS 7 implements "Configuration Locking". This is to help with IIS administration.

Here, look at the error details and how to resolve the same: IIS 7 – This configuration section cannot be used at this path.[^]

As per it, one of the resolution:
1. Open the applicationHost.config file, located here: %windir%\system32\inetsrv\config\applicationHost.config
2. Edit the "handlers" section.
3. Change this line:

XML

<section name="handlers" overrideModeDefault="Deny" />
To:
<section name="handlers" overrideModeDefault="Allow" />

1. Handlers line does not exist in web.config file.
2. There is no IIS Admin here , i am running this on localhost...

Read that article provided by you but no luck :(

Yes , Got it... I had to change in the applicationHost.config file...
it is working now but new error has been generated which is

HTTP Error 404.3 - Not Found
The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.

It is possible that a handler mapping is missing. By default, the static file handler processes all content.
The feature you are trying to use may not be installed.
The appropriate MIME map is not enabled for the Web site or application. (Warning: Do not create a MIME map for content that users should not download, such as .ASPX pages or .config files.)
If ASP.NET is not installed.

I told that you need to modify applicationHost.config.

Now, you have different issue to troubleshoot. Use aspnet_regiis.exe to register version of .NET framework you are using.
