Windows machine 'C:\Program' not recognized as an internal or external command,

[catbears]

What happend: I installed in a new environment, set up the path like described. Except here I have a more recent version of image magic, so the IMCONV looks like this:
%PROGRAMFILES%\ImageMagick-7.1.0-Q16-HDRI\

Windows finds magick as a command, but when I do
dr-doc-search --train -i "pdfs\my_pdf.pdf" --embedding huggingface

There is this error.

'C:\Program' is not recognized as an internal or external command,
operable program or batch file.

It seems to me, that this is the problem: 'C:\Program' is not recognized as an internal or external command, operable program or batch file.

In Windows the folder is called Program Files and the space in the name is a reliable source of errors in my scripts. I don't really understand where it comes from in this case.
