.Net 3.5 Install Issue (Not related to security updates)

[Brandon P Turner]

Hello, everyone. I need to get .Net 3.5 Installed on Windows Server 2012 R2 so that we can install SQL server. I am an admin on the machine. I have researched the crap out of this and have tried the following...

• Checked for the two security updates from MS for .Net 3.5. They have not been and are not installed.
• Tried installing from the GUI
• Tried installing from cmd (elevated): DISM /Online /Enable-Feature /FeatureName:NetFx3 /All
• Tried installing from PowerShell (elevated): Install-WindowsFeature -Name NET-Framework-Core -Source "Windows Update" -Restart:$false -Verbose
• Windows Update gives me the error 800B0001. I can click "Check online for updates" where updates are available. Install all available updates (still do not include two .Net updates noted by MS to cause issues).
• I check Group Policy and disable prem WSUS server. Receive same results.
• Run everything again and check DISM and CBS logs:

This tells me what I already know. I made sure all firewalls are off. There is no anti-virus installed. I disable UAC. I am logged in as admin. I ran DISM cleanup and health check to no avail.

What the crap is going on, here? Anyone? Can I just download this from somewhere reputable? I don't have the installation media. Thank you!
