Exactly what I needed, thanks for taking the time to write this! Tried all different kinds of solutions to no avail. Only detail that I did not work out is downgrading to jpeg8. I haven’t used any tools that throw an error yet. If ever you have time to give it a look here is the error when entering $ conda install -f jpeg=8:

Solving environment: failed

UnsatisfiableError: The following specifications were found to be in conflict:

- jpeg=8

- poppler -> jpeg[version=’>=9b,<10a’]
