MYOB Accounting v 18 downlaod

Hi,

i have had v.17 Accounting then v.18 all going well. I still use the v.18 but have since switched from Windows 7 OS to Windows 10 and now need to reinstall the CD.

But, problem is the Windows 10 wont read the v.18 Install CD. I have the serial number etc, so can i downlaod v.18 from somewhere please?

Thanks in advance

Marc
