Hi Macolm, I'll be happy to help with this issue
Unfortunately Microsoft do not offer any upgrade path from Office 2010 Home to the Professional version
however, which version do you currently have
is it the Home & Student version?
or the Home & Business?
it is the latest Home and Business
which component of Office does the LEAP system require?
as some of them are sold seperately
I will have to find that out. Do I purchase the component from the microsoft website?
