I cannot install CKAN.

I have a problem with trying to install CKAN. It used to work just fine when I played KSP earlier this year, but after not having touched it for a while it did not work anymore. Trying to reinstall it and any subsequent attempts to install CKAN have only yielded this error message in the CMD-prompt:

I’ve tried running it as administrator and moved the .exe to another folder etc. in the hopes it at least would give me a different error message to pin down the problem, but I’m at a loss. If anyone has/had the same problem or knows how to maybe fix it, I’d be ever so thankful :)
