C # application license components and elements

If I have 5 target computers, and I'm going to install the application on one of these target computers. How do I prevent users from copying my application to other target computers?

To be clear, I do not want them to copy my application after installation (they should not copy my application from the installed application folder). The problem is that now I install and deploy my application using the installation and deployment of Visual Studio 2010, but everyone can copy my application folder after installation, for example, my application folder (exe, DLL and resources) is located in "Program Files / MyApplication, "In fact, they can copy my application from this folder and paste it onto other computers, and then use it. Of course, they can copy it, but I think that they will not be able to use my copied application? Is there a way to protect them from copying my application? Do I need to write additional code?

I am really new to software distribution. Please tell me what I should do. thank

You can use the Rhino Licensing framework to create a license file. It has a LicenseGenerator class that has a Generate method. Here's what it looks like:

 public string Generate(string name, Guid id, DateTime expirationDate, IDictionary<string, string> attributes, LicenseType licenseType);

The Generate method accepts the name of the licensee. A unique license identifier that can be generated as Guid.NewGuid (), an expiration date, and an attribute dictionary is where you can save a couple of custom keys in the license file.
