You may find it better to install the 32bit version of Google Earth regardless of your architecture. This is because the 64bit version of Google Earth is actually the 32bit version, but with modifications to make it run in a pure 64bit environment. As Mageia supports 32bit and 64bit applications natively, the Google 64bit compatibility libraries that come with the "64bit" package of Google Earth are not neccessary, out-of-date, and will often result in it crashing!
