i have tried time and time again to download the .net framework (framework 3.5 (inc net 2.0/3.0)) but it always fails saying how it can not find the file specified. i am running a lenovo ideapad 330 with windows 10 (ver 1803, os build 17134.345)
i have tried:
using the prompt - failed
using the manual install - failed
giving the system max perms - failed.
Are you trying to install it through "Windows 10 Features"
In case you need more information, here is a link:
Install the .NET Framework 3.5 on Windows 10, Windows 8.1, and Windows 8 | Microsoft Docs
Insert your install media & type at elevated prompt:
DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:D:\sources\sxs
You can try 3rd party installer (made by @abbodi1406):

OK, the Windows 10 Feature installation method should have been straightforward, but since that errored out as well, something else seems to be going on with your Windows, so wait for somebody with more experience to suggest a way out.
In the mean time, if you haven't already, you could give muchomurka's suggestion a go as well with the elevated prompt and an install media to see if it works. The following link shows the detailed steps involved.
