Windows 2003 / ASP .NET 2.0 / Sharepoint 2007

i am trying to install Office Sharepoint 2007 into a VM.
I ran in the following error:
---------------------------Setup Errors---------------------------

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.
---------------------------OK ---------------------------

It's right, ASP .NET 2.0 is not in the web extension list ! :'(

I tried adding it manually..no way.

I installed .NET 2.0 over the existing one. Works !

Damned IIS that doesn't like to get installed after .NET
