I have installed pandoc on windows via the instructions at
https://pandoc.org/installing.html. However, this installs an old version - see below. I have attempted the zip file etc, but it is all the same.
C:\>pandoc --version
pandoc 1.19.2.1
Compiled with pandoc-types 1.17.0.4, texmath 0.9, skylighting 0.1.1.4
Default user data directory: C:\Users\paddy.mccrudden\AppData\Roaming\pandoc
