#Google earth download problem install
This direct install link installs the older 7. According to the Earth forums the direct install version available here has the update feature disabled.
The only fix that got it working again for me on my 64bit systems (and as described in several Google Earth forums) is to remove the newly updated Goggle Earth and reinstall the older 32 bit version available here. This latest earth update will happen on machines running the Chrome browser as Google's updater apparently when it runs, will update all Goggle origin installed software e.g. It would take more work than I have done to fully quantify this. This newest update apparently when installed on 64 bit systems appears to be (the first?) full blown 64 bit version, so we may be seeing behavior differences between 64 bit versus 32 bit systems. I did change the /regserver command to reflect the new location that the newest 7.3.xxxx version installs to which is different from previous versions, at least on 64bit OS machines (These observations were on two Win 7 Pro 64bit OS machines).
There is quite a bit of discussion about this on the Google Earth forums. From what I have seen on two of my computers, the newest Google Earth Pro update (7.3.xxxx) just released around 2/1, breaks the Basecamp to Earth link in a manner that the referenced /RegServer registration did not correct.
