Visual studio install offline installer with no network

Question

I am trying to install Visual Studio Community 2019 to a set of offline computers. I have followed the Visual studio instructions precisely and i have created the offline cache folder with all the files and .exe however when i try to install Visual Studio using the offline installer i get a prompt that it is "just getting things ready" then shows a window which attempts to download packages but again i have no network on these computers and i am really scratching my head as to why a OFFLINE installer is trying to connect to the internet...

What the hell is it doing and can i get it to skip this step somehow ?

here is what i have done:

1: Download the Visual Studio Comminity 2019 bootstrapper from:

https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=community&rel=16&utm_medium=microsoft&utm_source=docs.microsoft.com&utm_campaign=offline+install&utm_content=download+vs2019

2: Rename the downloaded Visual studio bootstrapper to vs_community.exe.

3: Within the CMD window enter: vs_community.exe --layout C:\vslayout --lang en-US

where C:\vslayout is the folder which shall be created and used to store the offline installer so change the path and name as preferred.

4: To install Visual studio using the offline installer, open the offline installers and run the setup.exe

But i get these dam windows popping up?

Before we get started we need to setup a few things...

Installer downloading files

Answer 1

OK i managed to solve this issue. I first needed to install the certificates to the local machine either from the certificates folder which is inside the layout folder or by right clicking the setup.exe and then Properties - Digital signatures - click on the item in the list then click Details - view certificate - install certificate - Local machine and then just continue the process with the defaults.

Then once the certificates are installed i then run the .exe as administrator and it works :)
