The Unity Download Assistant supports offline deployment. This allows you to download all the necessary files for installing Unity, and to generate a script for repeating the same installation on other computers without internet access.
Run the Download Assistant, and install Unity as normal on one computer. This computer must have enough free disk space to download all the files. Click the dropdown and select Custom, then choose the location you wish to download the files to.
Open your PC’s file manager, navigate to the custom location folder you specified earlier, and look for the
.bat file inside that folder. Check the contents of this file. It should look similar to the following example:
install.batfrom the Administrator shell. In the Start menu, search for
cmd.exe, right-click, and select Run as administrator.
