Windows – “Turn Windows Features on or off” when installing .NET 3.5 SP1

.net frameworkinstallationwindows 7

I am trying to install a program on my Windows 7 machine and it says that I need to have .NET 2.0 or later installed. Since Windows 7 comes with .NET pre-installed, I called support and they told me to just re-install .NET since my .NET install is probably corrupted. The program I am trying to install is SNGWiz. I do not think its installer is borked.

However, when I install .NET 3.5 SP1 using the download from the Microsoft .NET web site, I get the following error:

You must use 'Turn Windows features on or off' in the Control Panel to install or configure Microsoft .NET Framework 3.5 SP1.

I have gone to the Windows Features on/off panel and have turned 3.5 both on and off and have tried to re-install .NET 3.5 SP1 under both situations. But it has failed with the same error.

What can I do?

no i am with the origional poster, even just switching it on doesnt help, try and update the .net framework with it on or off gives no difference, try to install the software after switching it on achieves nothing to, this is a major flaw in the system,
