The expression "up and running" means that something is working or operating properly. It is often used to describe a machine, computer program, or system that has been set up correctly and is now functioning as it should be. For example, if you have just installed a new software program on your computer, you might say "I finally got the program up and running" when you have successfully launched and used the software for the first time. Similarly, if a business has just opened its doors for the first time, they might say "We're finally up and running!" to indicate that they are officially open for business and operating smoothly.
