"can't download the software because of a network problem" in Boot Camp Assistant High Sierra/Mojave

(Sorry couldn't find edit button)

• Firewall on/off same problem

• "xcode-select --install": note: install requested for command line developer tools

So with the xcode-select -install command I click "install" and get the *SAME* "can't download the software because of a network problem" message.

So I am looking at https://en.wikipedia.org/wiki/Boot_Camp_(software)#Boot_Camp_Support_Software_(for_Windows)_Version_History trying to find a good version and see I need version 6.1.6655 or above ... I then try my luck on https://support.apple.com/downloads/boot%2520camp%2520support%2520software%25206 which has a terrible search filter/query standard but ok ... and find nothing but old versions. Great so I can't find a manual work around :/ .

Also got the CLT from https://developer.apple.com/download/more/ for 10.2.1 (latest version as of writing) ... problems remains. Frustrating.

After providing a location (screen after the initial click) and clicking "Save" the same thing happens.

@LonerT:

Also unless line 3 is important (I'm guessing no since I reach the final hop) this works too;

Hosts file seems normal. I can run local/web applications just fine and have changed nothing specific in this regard before trying the boot camp assistant.

MappleTondev$ cat /etc/hosts

I have downloaded and run Brigadier:

Done.

So now I am looking at:

But I can't seem to point the Boot Camp Assistant to this dmg file ... does it have a default location it picks it up from I can place it (maybe in a standard/default folder name)?

@LonerT, found another thread (somewhat) related and placed the WindowsSupport.dmg file in a Library/Application Support/BootCamp* folder (I had to create the BootCamp folder). After I run the Boot Camp Assistant ... it still fails with the darn message and deletes the .dmg file in that folder (leaving the folder intact).

Grrr, why can't this simple download step function normally, this feels so buggy :( .

Also found https://support.apple.com/en-us/HT209351 ... I tried with April version, doesn't change a thing about this warning message or problem.
