Product Activation Issue

I uninstalled SolidWorks 2023 and installed SolidWorks 2024. I have a license key and downloaded it, however when trying to activate the license, I keep receiving the message below:

 

"The current computer identifier (0) does not match the previously used computer identifier (1). You can continue, but you might have activation or deactivation issues in the future."

Then, when I try activating it produces an error. How do I fix this?
