Hi for a while now I have had this issue. Every time I try to install .Net framework 3.5 it give me this error code (0x800F0906) and tells me to make sure I'm connected to the internet. Any ideas how to fix it?

4. After uninstalling the updates, try to install .NET Framework 3.5 again using any method and this time it should install without any problem.

Windows 8.1 has inbuilt net framework 4.5. No need to install 3.5. ....

1. Type gpedit.msc in RUN or Start search box and press Enter. It'll open Group Policy Editor.

2. Now go to:

Computer Configuration -> Administrative Templates -> System

3. In right-side pane, look for "Specify settings for optional component installation and component repair" option.
4. The option would be set to Not Configured. Double-click on it, set it to Enabled and enable "Contact Windows Update directly to download repair content instead of Windows Server Update Services (WSUS)" option.

That's it. Now try to install .NET Framework 3.5 again using Control Panel -> Programs and Features or by using DISM command and now you'll not face any problem.

Consider a game requires 4 GB ram and you have 8 GB ram, then will you install 4 GB, answer is no. Because that game can run with 8 GB ram. Same here, that programs will work fine. ....
