Doesn't automatically detect fillable form
I have to fill in 2 fillable forms, but when I open the files in acrobat reader, it won't automatically recognise them as being fillable. Do I have to activate something that allows this? I understand that it should come up automatically with red boxes that I can click on, but it doesn't.
I have checked for updates but there weren't any. I have also deleted the programme and reinstalled it, but it is exactly the same. Has anyone else had this problem? Is there something I can do to solve it?
