In an attempt to get rid of more than 50 malware infections, I have had to do a clean install on my iMac and are now trying to reinstall my old programs one by one, only to find the new Sierra 10.12.6 O.S. will not accept the FileMaker v. 11 installer. And now, after spending a few more hours I find, I cannot upgrade to v. 14 or v.15 without having a previous version installed on the computer. Is there a work around that 80 year olds can follow?
Thanks for any help,
