Hello everyone. I user Mathtype for my typesetting needs. Unfortunately the capital script letters are not included. I have been told I can download the font needed (mathrsfs) from the internet. I have searched and found a lot of downloadable packages (namely fromt ctan.org) but they all say I need some kind of different compiler or something. Does anyone know where I can get this font and give a quick explanation of how to download it and install it in my fonts folder?

Thank you so much in advance.
