Hi Don
Thank you so much for your help and clear suggestions, its all compiling without errors now. It has, however, been a difficult process to achieve the installations. I was using Windows XP and the Windows x86 (32-bit) didn't seem to do anything when launched, I found an app to cure errors and also un-installed java but still couldn't install new version. I have given up with that at present and used a Windows 10 VM which personally I don't like (I am a long term Mac user) but the installation went relatively smoothly despite a Windows update halfway thru and the VM running out of space (the joys of computing).
Thanks again.
