They are split RAR files. You need to download all 6 parts into the same folder, then point WinRAR (or similar) at part 1. That should unzip all 6 parts into an image file. Then use ImgBurn (or similar) to create a disc from the image file.
The other 660 people that have downloaded the files haven't reported a problem.

I could not unzip the files, part 1 and 2 are protected by a password, can you please provide the passord or explain how to unzip the files because I'm havien a hard time ^^ thank you !!
