I am using Microsoft Word 2011 on my iMac (OS X El Capitan 10.11.5) and it is giving me loads of grief. I am considering buying from you, the latest Word programme but am worried about all my 'old' Word files conversion if I download the new software could you put my mind at rest and talk me through the safest installation at the same time providing me with any links I will need to travel through.

Thanks Ian

Your documents should be fine. However, before you do this, you should know that Word 2016 does not have grammar checking. MS has been promising it for about a year.
