(Sharepoint 2010 Central Admin) Internet Explorer cannot display the webpage

To resolve this problem, you must use the ASP.NET IIS Registration Tool (Aspnet_regiis.exe,) to register the correct version of ASP.NET. This can be accomplished by using the –iru parameters when running aspnet_regiis.exe as follows:

aspnet_regiis.exe -iru

thanks, but when i try to run the command aspnet_regiis.exe -iru , I get an error that it is unrecognized.
I am using command prompt to do that.

Can you please tell me the steps involved in registering correct version of Asp.net.

So browse to the correct folder for the .net version you are running then run then command.

Example: open command prompt then enter cd %SystemRoot%\Microsoft.NET\Framework\v4.0.30319

NOTE: When running aspnet_regiis.exe, you must ensure that you run the version supplied with the .NET Framework version that you want to use. The .NET Framework 4 version of aspnet_regIIS.exe is located in the following path(s):

32-bit systems: %SystemRoot%\Microsoft.NET\Framework\v4.0.30319
64-bit systems: %SystemRoot%\Microsoft.NET\Framework64\v4.0.30319

Okay, asp.net is now registered succesfully.
i am now able to open "http://localhost" 
But, when I try to open central admin, I get an same error "Internet Explorer cannot display the webpage"

Does anything stand out in your application logs?  Any errors?  Make sure you have the sharepoint services running.  Did you select a specific port to install under?  Like http://localhost:9000 or something?

the port i am using is 14207
I don't see any errors in logs under 14 hive.
Can you please tell how to check whether sharepoint services is running or not.
thanks for your patience with me

So to access the admin page you need to enter http://localhost:14207
Did you try that?

Yes, I tried it but still the same error "Internet Explorer cannot display the webpage"
I also want to mention that I am installing it on Windows 7.
I used the setup wizard but to create the sharepoint_config and admin_content databases, I uses the powershell. (I didn't install it using the wizard).

It finally worked.
Here is the issue I was facing.
I ran the Configuration Wizard half-way. I created Shrepoint_config and admin_content databases using Powershell.
But, after that I didn't run rest of the configuration wizard and I was directly trying to open the Central admin.

Thanks for your help...appreciate it.
