I have an Excel file. When I provide it to someone, I want that particular file to open up on their computer (or whichever computer they open it on) only and no subsequent computers. So I am essentially looking for a way to have an Excel file tied to one particular machine.
I don't have the necessary knowledge to say what software or solution I want for my needs, nor do I know what budget I would need, so I would like freelancers to provide a proposal with a suggested solution to this problem.
I have thought about getting a small piece of software which the Excel document would be linked to and only opened through that particular piece of software. And this particular software could only ever be installed on one machine.
I look forward to your suggestions.
