aspnet_isapi.dll missing in installation in IIS7 windows server 2008 R2 Web

Hi all,

I'm installing .Net Framework 4.0 in a dedicated server but i can't find aspnet dlls in the normal folder.

I'm using : dotNetFx40_Client_x86_x64.exe as installer.

And looking for the files in the normal folder: C:\Windows\Microsoft.NET\Framework64\v4.0.30319

Run all the updates etc. but those files never appear so i can't allow the ISAPI later.

Any ideas?

Thanks in advance.
