I don't know what to do to contribute an updated crosstie, but this is pretty straightforward: Google Earth standard edition works now, in both OpenGL and DirectX modes, not crashing on Linux where the native Linux version likes to crash like crazy. It installs and runs fine with in a WinXP bottle. I'd give the rating 4/5 stars for application version 7.1.5.1557, CrossOver version 15.1.0.
(EDIT: It has one dependency, MSXML 3.0. This is needed to make Search work.)
In order to install properly, the "offline" installer is required, which is available at the following URL (automatically provides the latest version): https://dl.google.com/earth/client/advanced/current/GoogleEarthWin.exe
The only caveat is that the "tips" window at startup almost always obscures the (modal) dialog at first startup which asks whether to enable DirectX mode, and that makes the modal dialog seem inaccessible (the tips window has a Wine-rendered border and can't be dragged). The easiest fix is to pre-enable DirectX mode, which would be this registry setting:
[Software\\Google\\Google Earth Plus\\Render]
"RenderingApi"=dword:00000000
Alternately, to let the dialog show, tips could be pre-disabled by default instead, which is:
[Software\\Google\\Google Earth Plus]
"enableTips"="false"
The only feature I haven't found to work correctly is the Tour Guide "filmstrip" which has a strange foreground subwindow that doesn't shrink properly when minimized. This can be pre-disabled (recommended):
[Software\\Google\\Google Earth Plus\\TourGuide\\Filmstrip]
"Enabled"="false"
All registry settings above are against user.reg.
