not helpful you have file extensions hidden but chances are the second screen shot shows the iso file you need as the 3rd shot shows the contents of the iso file that you extracted from the second shots file
don't know why people still use winrar it causes more issues than anything else
uninstall winrar (or if you want to keep it remove the file association with iso files so they do not show as winrar files) go get 7-zip and use that for extracting instead
