I've got current version of Google Earth Pro (7.3.2.5776) but look like there is no connection.
Only message is:
Wait Google Earth initializing
Google Earth is not initialized completely, please check if your Google Earth could work fine or initialized then try this function again.
I found installers at link below but not sure which version and 32/64bit

Thanks!
Here's a link to a recommendation from
Makai SmithDirector, Product Management MicroStation Product Line
Recommended version of Google Earth Pro
Please use 32 Bit Google Earth version. 64 Bit version will not work.
Thanks,
Manoj
