Where are/were you saving the update to? This is a Permissions Issue unrelated to WiX. I can say that because of your statement regarding the desktop: - Any User will always have full Read/Write Access to their desktop.
This means that whatever Folder you were pushing the update to, the logged in user had no Write Access to. In that case, use a location like %temp%, or %homepath% or %appdata%.
