This product requires ASP.NET v2.0 to be set to ‘Allow’ in the list of Internet Information Services (IIS) Web Server Extensions.

Summary of Issue

When trying to install Microsoft Windows SharePoint Services 3.0 you receive the following error:

Setup is unable to proceed due to the following error(s):
 This product requires ASP.NET v2.0 to be set to ‘Allow’ in the list of Internet Information Services (IIS) Web Server Extensions. If it is not available in the list, re-install ASP.NET v2.0.
 Correct the issue(s) listed above and re-run setup.

Methods to resolve the problem

In my case the .Net Framework was installed but it wasn’t in the Web Services Extensions list. I’m assuming this is because I installed IIS after the .NET framework.

1. To fix this error you will need to open up a command prompt window and change your directory to “C:\Windows\Microsoft.NET\Framework\v2.0.50727″ and run the command

user@computer:$ aspnet_regiis.exe -i

2. After this command completes successfully you will need to open up IIS Manager and go to Web Service Extensions and mark ASP .NET v2.0.50727 as Allowed if it isnt already.
