[NTG-context] Installation on a PC

Dear Group, I am a Mac user and have had many happy years using ConTeXt. I now need to install ConTeXt on a PC (Windows) and this has been troublesome. Is anybody able to point me to a foolproof method? (I started this mail with all of our errors but reasoned that somebody might know the answer to the more simple question.) Thanks in advance. — Nigel nigel@nigelking.me.uk
