Software Serial number and activation removal

I'm looking for an experienced developer to remove the activation and registration procedure from an old Labeler software running on Windows. I have the original CD but no serial number, and the company that created it is defunct.

Requirements:
- Modify the software to bypass activation/registration
- Ensure it runs smoothly on Windows10/11
- No updates or patches available

Ideal Skills:
- Proficiency in reverse engineering
- Experience with Windows software modification
- Strong problem-solving skills

Please provide a brief outline of your approach and estimated timeline.
