I can't seem to find a specific answer to this.  I am sure this will be an easy one for most of you.

I have a Windows 2003 R2 Server with Service Pack 1.  It does not have any of the .net Framework installs on it at all.  Do I have to upgrade to R2 Service Pack 2 to install .net Framework 4 on it first?  

Also, do I have to go through Control Panel/Add Remove Windows Components and install .net Framework 2.0 first prior to running the .net Framework 4 install or can I just install .net Framework 4 from scratch?

Thanks so much for your help!!

See below the .net 4 Requirements, as you can see it does require SP2 for server 2003.  You do not have to install .net 2 first unless the application you are using specifically requires it.  Also you will have to isntall .net 3 or 3.5 if your app uses it.   You can download .net 4 from:  http://www.microsoft.com/en-us/download/details.aspx?id=17851  

However i highly reccomend using Microsoft update instead to update  to .Net 4 https://update.microsoft.com/microsoftupdate

Thank you for your post!

In your comment "See below the .net 4 Requirements, as you can see it does require SP2 for server 2003."  I have Server 2003 R2 with SP1.  Is this the same for Server 2003 and Server 2003 R2?

Do you mean that if there is no indication in our support materials from the application, I can just install the full .net 4.0 from the beginning and not have to install 2.0, or 3.51?

Will I have to install IIS and aspnet as well?

I appreciate it so much!!

No Server 2003 SP2 and Server 2003 R2 are not the same, it looks like Microsoft has forgotten to add the R2 Version to the System Requirements.  However R2 version was released after the SP2 for Server 2003 so therefore you will not need to install any Service pack.  You should be able to install .net 4 right away.  Best way to be sure though is go to Microsoft Update (https://update.microsoft.com/microsoftupdate)  and see if .net 4 is on the download list.

Yes, if you app only requires .net 4 then you only have to install that, you don't have to install older versions.
