Ok, I know you are sick of me, but you are my hero and I have another question

... I went to the link and followed directions to the t... one threw me off and that was changing the TIFF Parameters, is that just saying to change permissions or something else. Ok, so I have a couple of questions... then it is asking for my path to my mogrify file, but there are so many that I don't know which one it is... where is that main file in the download and I can plug in the rest of my path.
And last but not least, I am still having a problem with the Magick++ file. When I try to open this file it won't let me because of the special characters, and it says the file is invalid. Is this normal...how can I get around it.
Thank you so much for your help- I am pulling my hair out!
