I recently had my Windows 7 computer crash on me. I've traced many issues. One remains causing blockages from my Windows installler/uninstaller from working. The google earth plug-in is specifically causing the windows installer server from being accesses. The message reads "an installation for Google Earth Plug-in is currently suspended. You must undo the changes made by that installation to continue." I tried that but with no correction. Following, I then get the message "The windows installer service could not be accessed. ..... contact service support etc."
This appears to be a conflict problem between windows 7 and your plugin application. Can you provide me with the fix?
