ERROR: do you have ImageMagick and GZIP installed?

I keep getting this error, not sure if there is incompatibility with newer versions of ImageMagick & Gzip? was wondering if you had any insight.

I had the same problem. The newer versions of ImageMagick are indeed incompatible, because the 'convert' command is deprecated. It now uses either just 'magick' or 'magick convert'.

I fixed it with finding an older version that you can download from Npackd: https://www.npackd.org/p/imagemagick64/7.1.0.4
(I could not find any older versions on imagemagick's own page)

Hope it helps!
