Have you tried reinstalling Earth 5? Also try this:
1. Open My Computer
2. Go to Tools > Folder Options in the menu.
3. Click to 'File Types'
4. Scroll down to KML and KMZ
5. If "Opens With" is not "Google Earth" for both of these, use the
Change... button to make sure that Google Earth is associated with
those file types.
Also, please use the Google Earth Help Center at:
for installation and file association problems in the future.
