Hi Brianahsmiles,
Welcome to MSDN forum.
According to your description, what's your Windows system? Could you tell me how you install the .NET Framework 3.5? I suggest you take the following steps to install the .NET Framework 3.5:
#1. type “Turn Windows features on or off“ in the start search box and open it.
#2. Select .NET Framework 3.5(include .NET 2.0 and 3.0) check box, press
OK and wait for installing, then restart your computer.
Based on the error code “0x80070002”, I suppose it is caused by your Windows Update. Please update your Windows to the latest version, if you encounter a Windows Update error, please use the
DISM tool to fix it.
BTW, if the issue persists, I need your help to collect more installation logs. Please download and run this
collect.exe tool, go to %temp% folder and find the vslogs.zip file, upload it to
https://onedrive.live.com/ and share the link in here.
Hoping everything goes well.
Best Regards,
Anna
