Windows 7 .NET Framework 3.5 question

[cwpatterson1]

After sensing that there may be some problems with .NET Framework 3.5, I decided to reinstall it. I uninstalled it and downloaded the install file, but the install file wouldn't run. I then found out that .NET Framework 3.5 is either enabled or disabled using the "Turn Windows Features On Or Off" tool in the Control Panel. I made sure all parts of .NET Framework 3.5 were enabled, but when I checked the list of programs installed on my computer it wasn't there. I figured that if .NET Framework is meant to only be enabled or disabled, Windows wouldn't let you fully remove it, but I guess I have. I tried installing some other software but certain components failed to install and it might be because they need libraries from .NET Framework 3.5.

So: Have I actually removed .NET Framework 3.5 from my computer? If so, how can I reinstall it if the install file refuses to work? If not, why does it not show up in my list of installed programs?

Thanks for any help!

It seems like the situation with your .NET Framework 3.5 installation is a bit tricky. Here's a breakdown of your queries:

1. Removal of .NET Framework 3.5:​

When you use the "Turn Windows Features On or Off" tool in the Control Panel to disable the .NET Framework 3.5, you are essentially turning off its functionality, not completely removing it from your system. The components are still present on your computer; they are just disabled.

2. Reinstalling .NET Framework 3.5:​

If you suspect that the installation file for .NET Framework 3.5 is not working correctly, you have a couple of options to try reinstalling it:

Option 1: Install .NET Framework 3.5 from Windows Features:​

1. Open the "Turn Windows Features On or Off" tool again.
2. Check the box next to ".NET Framework 3.5," click OK, and follow any on-screen instructions.

   Option 2: Using DISM Command:​

   You can also use the Deployment Image Servicing and Management (DISM) tool to enable the .NET Framework 3.5:

   dism /online /enable-feature /featurename:NetFx3 /All /Source:

   Replace with the path to your Windows installation media (such as a DVD or mounted ISO file).

   3. Missing .NET Framework 3.5 in Installed Programs:​

   It's common for .NET Framework versions not to appear in the list of installed programs in the Control Panel, even though they are integral parts of the Windows operating system. This behavior is because it is a Windows feature rather than a standalone program.

   Additional Information:​

   • If the components of .NET Framework 3.5 are still not functioning properly after attempting to reinstall, you might need to run Windows Update to ensure all related updates are installed.
   • For software installations that require .NET Framework 3.5 components, make sure to have the feature enabled to avoid any issues during installation.
   Try these steps and let me know if you encounter any issues during the reinstallation process.
