Run Ruby Script in Elevated Mode

Run ruby script in elevated mode

Here's how to do it. The easiest way is to restart your executable with elevaded (Admin) privileges using ShellExecute.

With Ruby you do it like this:

require 'win32ole'

shell = WIN32OLE.new('Shell.Application')
shell.ShellExecute('path_to_ruby_program', nil, nil, 'runas')

If you have Windows UAC enabled this will give you the familiar Windows pop up dialog that requests Admin privileges. Once you click Yes, your process will run with Admin rights.

The secret trick here is using the the undocumented ShellExecute operation parameter runas, which will elevate the requested operation.

How can I execute Ruby scripts and irb from Windows7 Powershell?

Is the directory that Windows Ruby Installer installed to (like C:\Ruby192\bin) on your path? I can't recall if it should add that automatically on install but I've not had any issues running irb or scripts from powershell. You can check if it's on your path by running the following from a powershell session:

$env:path
