Wanting to prompt user to open form in Adobe Reader

I recently made a post that some forms I made in Acrobat which are being used by the public are not conforming to the rules I set when creating the forms, such as only allowing text in a box to go to the length of the box (no scroll). Also, some forms I've received have entered text which is duplicating over itself and text continuing past the width of the box instead of entering onto a new line.

A few people on that post had replied to say that this is most likely because the people using the form were using a PDF reader which did not recognise the restrictions I added to the form.

It was suggested that I edit the file so that users are prompted to open the file in Adobe Reader. How do I do this?

If there are other solutions for how to fix these issues, I'd love to here them.
