But, here's the catch, I don't have any Internet access on my network. The installation guide provides a solution for this kind of scenario - install the ESP on a computer with Internet access, after the components are downloaded you can abort the installation and transfer the components any way you want to your LAN.
This is a very strange solution, why run an unnecessary installation? What if I have limited privileges on my Internet computer?
After all, there's a much simpler solution - why not provide me with the links to the components? After all, what I did was to harvest the links from the manifest.xml the installation uses to download the components...
Why make me sweat?
