Go to http://earth.google.com/intl/en/downloa ... anced.html and take out the tick saying "Allow Google Earth to automatically install recommended updates." now you can download the full google earth installer.
then also install something like UniExtract.
Right click on the GoogleEarthWin.exe file and choose 'Uniextract to subdir'. This will then extract it all, and in the resulting folder are the files and the msi. Stick the entire folder on your deployment share, and set up your group policy to use that msi, and transform it with the 1033.mst file.
