I'm really going out a limb here politically, guyke. I don't really want to support DAZ products on TalkGraphics, a Xara-run forum, but here goes anyway, just this once ():

Your web browser might not have saved the files with the correct names. For example, if the Bryce content folder is 668,116, you did indeed download it but either your browser has stripped of hidden the file extension. Go to Control Panel, Folder Options, View first of all. *Hide Extensions for known file types* should be unchecked.

If an *.exe doesn't appear now for your download files, click to select the file name and then click to edit it, and they type ".exe" (without my quote marks!) at the end to label the property if the file.

If still no go, try a different browser, download to a different location, eh?

Sorry for this pause in Xara programming, folks!
