Common issues: Maybe crashes, missing toolboxes, or compatibility with newer toolboxes? Solutions could involve using the MathWorks support or applying specific patches. Also, pointing out where to find support, like documentation or forums.

Also, mentioning alternative versions or how users can access MATLAB 2012 through educational institutions or company licenses. Maybe include examples of scenarios where MATLAB 2012 is still utilized, like in certain industries or academic research.

I should also consider the ethical and legal aspects. Using unlicensed software is illegal, so I must stress the importance of valid licenses. Also, security risks with outdated software, like lack of support for modern security features.

Let me structure each section step by step, ensuring that each part addresses the user's needs and provides practical guidance. Also, check that all the necessary information is covered without making it too lengthy. Maybe include bullet points for installation steps or common fixes to enhance readability.
