Either the dlls or a different ZView version will be included in the next release.

Until then, you can use just any other image viewer instead of ZView. ZView is not really part of Zorro, but just an open source image viewer. Anything that displays PNG files - f.i. the Windows fax viewer, or Irfanview or any other image program - will do as well. Zorro creates the chart images in the Log subfolder.
