Hi, I purchased a Humble bundle but I am unable to download through the links given, I keep getting an error with the Magix installation manager as seen in the attached photo. How can I go about correcting this issue?
Unfortunately the error "message" you show is not at all helpful, is it? That is not your fault, clearly.
However, what Magix program(s) are you trying to download/install? There have been a number of reports in the forums, spread over several weeks, where users have experienced problems with downloading their software. It might be possible that you could access your software download directly, which is why it would be really helpful to know what you have actually bought!
