Most of the sites of been reading this evening, are saying get off 7 asap if you can. if you cant make sure you have both Anti Virus & Malware and keep updated, make sure MS Office is still downloading patched ie office 365, use either Firefox or Chrome and keep updated, and do not use internet Explorer at all (although I don't think anyone uses IE anyway). Also remove the admin rights from day to day user accounts. So I can do all this, but still need to tell my Dad this should be temporary and needs to find replacement software asap. They do have a windows 10 PC each as well just this one piece of software wont work on anything but win 7 32 bit. I could try making a VM and say if youmust use it work in the VM Bubble
