1) Upgrade the VDA software to the version of 5.5. According to the prompt information comes from the interface while running the Google Earth in the DiretX mode, it requires to configure the system’s color as 32 bit true color. The current VDA installed in the virtual machine just supports 24 bit, and the VDA 5.5 supports 32 bit. Therefore, we just need to upgrade the VDA software. (As the VDA 5.5 hasn’t been commercial, we can’t use it as the commercial project, we must confirmed the special publishing time with the researcher, we can communicate with the researcher independently if the testing site needs it. We can also not upgrade the VDA, as the experience from the other sites where have tested the Google Earth, it’s not necessary to upgrade the VDA to the 5.5 version but only to implement the installation optional package “d3d9.dll” in the forth step, and then it can also support the Google Earth running as the DirectX mode. You may try not upgrading the VDA, but this case is based as it has been upgraded to the VDA 5.5.)
2) Install the DirectX 9.0c or the higher version DirectX plug-in module (we can search in the website and download it). Because according to the error prompt, only the DirectX 9.0c or the higher version DirectX plug-in module can support the Google Earth running as the DirectX mode.
3) Download the newest version Google Earth software from its office website (in this case is: 22.214.171.12401). Because we find there are some foggy areas while using the old version Google Earth.
4) Install the optional package (OptPackforGoogleEarth.zip, we can get it from the researcher) to the installation catalog of the Google Earth. I.e. copy the file named “d3d9.dll” to the catalog where the “GoogleEarth.EXE” file is in.
5) Select “Start” -> “Program” -> “Start Google Earth Pro in DirectX mode” (as the following picture 2 displayed), we can use the Google Earth fluently.
