I have a computer next to me. It's not connected to any network. I have just spent the whole night fighting BIOS settings to be able to install Windows 10 on it.
I'm going to use it for one single task (digitizing VHS tapes), which means I have zero need for it to ever connect to anything.
When trying to install the Elgato Video Capture software, it complains about .NET Framework 3.5 not being installed. And they link to the Microsoft webpage where it's available. Of course, that page defaults to the minimal "online" installer, which is just an EXE which downloads the actual data over the network. So, on the same page, I hunted down the fine-print "offline installer" link, which is of course much bigger, and transferred over it (via an USB stick) to the offline computer.
But I get the same damn generic "0x8024402C" error even with the offline/full installer! It acts as if it's trying to "download" data, even though it's all supposed to be in the 200+ MB EXE file. That's the whole point of it being a "full"/offline installer.
Yes, I have restarted the machine, as it suggests itself. That did nothing whatsoever. Same error.
Online, there's of course tons of articles about this, all telling you things related to "fixing your network connection"... But there is no network connection to fix since the machine is supposed to be offline. That's why I got the offline installer.
What can I possibly do now?
