CD with data not opening in selected application
it's reasonably simple to change the default application (the process is quite similar to that on windows)


Use Finder to find the file you are trying to open.
Right Click (or Ctrl left Click) Choose "Open With" -> "Other"
Use the resulting finder window to find the application you want to open the file with (you may need to change the "Enable" drop down to "All Applications")
Tick the checkbox, "Always open with"
Click "Open"
