We need php7 or higher for 3.2. We couldn’t remember existing version so had to do Method1 no 4 in the wikihow version.
In future, I will add the version number into readme or another textfile in the php folder at time of install.
Before installing 7 we have copied existing PHP (and I’ve saved in a folder called version no e.g php5.3…)
We have downloaded Moodle 3.2 but need to change some php7 settings and in IIS (post with all steps to follow tomorrow).
