How do you register ASP.NET 4.0 manually?

[scott slack]

I'm just learning ASP.net but having hard time setting things up. When I try to run a helloworld thing in visual studio. I get and error say I must register manually to server. and I get this error in explorer:

Internet Information Services 7.5
Error Summary
HTTP Error 500.21 - Internal Server Error
Handler "PageHandlerFactory-Integrated" has a bad module "ManagedPipelineHandler" in its module list Detailed Error Information
Module IIS Web Core
Notification ExecuteRequestHandler
Handler PageHandlerFactory-Integrated
Error Code 0x8007000d
Requested URL http://localhost:80/ASPexample/HelloWorld.aspx
Physical Path C:\inetpub\wwwroot\ASPexample\HelloWorld.aspx
Logon Method Anonymous
Logon User Anonymous
Most likely causes:
•Managed handler is used; however, ASP.NET is not installed or is not installed completely.
•There is a typographical error in the configuration for the handler module list.
Things you can try:
•Install ASP.NET if you are using managed handler.
•Ensure that the handler module's name is specified correctly. Module names are case-sensitive and use the format modules="StaticFileModule,DefaultDocumentModule,Di rectoryListingModule".
Links and More InformationIIS core does not recognize the module.

I've tried reinstalling ASP.net but still have same problem. What do I need to do to get this working so I can start learning?

I'm not sure if it is a .NET 4.0 Framework problem, but I would suggest that you check to make sure that it's installed (do this through your sever manager).

If that doesn't fix the problem, then I suggest that you try republishing your application and make sure that all of the components required by the application are included in your published package that you're moving to the web server.
