You will need to use a license file to install your product without an internet connection. You can manually copy your license file to the location specified by the INTEL_LICENSE_FILE environment variable. By default, your INTEL_LICENSE_FILE environment variable points to the following locations:
Windows*: C:\\Program Files (x86)\\Common Files\\Intel\\Licenses
Linux*: /opt/intel/licenses
macOS*: /Users/Shared/Library/Application Support/Intel/Licenses
During installation, choose the option that activates your product using the license file.
