NET Framework 3.0: Turn Windows features on or off

[chuckbam]

I though I had NET Framework 3.0 installed in windows. But, a custom Side Bar program told me to install it. I did not think it would hurt anything.

It wants me to "Turn Windows features on or off"
Does it want me to Turn ALL Windows features on or off? One time I turned on all features thinking that would be good (except for Indexing) and I received some service errors. I really don't want to turn of all features, not even for one re-boot or installation. It just does not sound like a good Idea. I think they should not have that requirement.

Then I read that you don't need to turn off all the features, just selected ones.
That did not work for me. Can anyone provide some information on this?

4.13 FileNotFoundException Occurs When Running ServiceModelReg.exe on Windows Vista
On Windows Vista, ServiceModelReg.exe may fail with the following message:
System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Web.Administration, Version=7.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

This is due to an incomplete installation of the Windows Activation Service (WAS). Ensure that all components of WAS are installed prior to running ServiceModelReg.exe. To do so, complete the following steps:



Open the "Turn Windows Features On or Off" dialog by clicking Start -> Control Panel -> Programs and clicking the "Turn Windows Features On or Off link."
In the tree view, select the "Windows Activation Service" checkbox.
Expand the "Windows Activation Service" checkbox and ensure the following sub-components are also selected:
- .NET Environment
- Configuration APIs
- Process Model
Click "OK" and wait for the components to finish installing.
Re-run ServiceModelReg.exe to register the WCF activation components with WAS.

These steps will install the minimal set of components required to support WCF service activation over non-HTTP protocols.
