I have been trying for a few weeks now to install iTunes on my computer. I am not very good with computers (I'm not bad either) but I can follow instructions very well. I have went online and tried multiple resolutions and nothing is working. What does this error mean and how do I fix it? I need iTunes so this is driving me insane that I can't install it.

Sorry if I posted this is the wrong section
Thanks for any and all help :)
