How to execute node-red project with zip of package files

I can't use 'npm install' because of company's security system.
But I have to execute node-red system on my computer.
I have zip file including require packages. (there are locales, nodered, resources, rules folder and many dlls.)

I searched how to run node-red project and I found 'npn start' -> 'node-red' -> get in the link
but if I order 'npm start' and 'node-red', I got throw exceptions because they can't find my package files.
How can I run it?
