Use RSA to sign a license file

Question

I am trying to figure out a way to stop people faking the license file that comes with my software. I watched RSA and used a signature to verify the data.

Now, from my understanding, I basically have some data (license file), and I use the RSAryptoServiceProvider SignData method to create a signature for the public and private key data that was created using ExportParameters (true).

Then I would provide the license file and public key using software so that I can check the data (license) on the client using VerifyData, but that should stop the user creating their own public / private key pair and recreate the data and just overwrite the public key and data?

I read and did some search queries, but I still stick to this, I'm pretty new to encryption and signing, but I need to understand this.

I know that it's almost impossible to protect a license such as a file, as if they just wanted to decompile the code and delete the checks, so I just want it hard for them to abuse the software, I don’t want them to they could simply compose their own license or transfer one license to another machine.

Can someone point me in the right direction or offer some advice?

Thank.
