Google Earth Pro to Model Maker 64bit fix

Start here: It might be a simple file-type association problem. Your Google Earth is not set up as the default app to open KML files. Here is the fix

If that does not work, check your Google Earth version, it may be too new:

If your Model Maker will not exchange data with Google Earth Pro, it is because your Google Earth Pro updated itself to version 7.3.3 or newer. Google Earth is at fault, not Model Maker!!! Google decided to remove support for external programs (like Model Maker) to connect to it and use its data in the latest version of Google Earth Pro.


Use your usual IT support provider, don’t call MMS Design for this. If you do, we will charge you a fee for the support on this matter since this is not a Model Maker Systems-related problem.


By downgrading your Google Earth to an earlier version that supports external app access will solve the issue. Step 1: Check your Google Earth version. If it is version 7.3.3 then you are affected.

  • In Google Earth Pro click on Help > About to see your version

Step 2: Uninstall your version 7.3.3 Google Earth Pro

  • Use IT support, don’t call MMS Design for this. If you do, we will charge you a fee for the support on this matter since this is not a Model Maker Systems-related problem.

Step 3: Download version 7.1.8 for your PC and install

Download links:

Google Earth

When you run this version and it tells you about a newer version that is available, please ignore it AND DO NOT UPDATE! This version (as far as we know) will not auto-update to version 7.3.3. For how long 7.1.8 will be available, we can not say.


You follow these steps at your own risk. MMS Design can not be held responsible for these steps. We supply this info because Google Earth Pro did not install itself properly on your PC, they slipped up not us. We do this out of our own goodwill to help our clients to repair your faulty/incomplete Google Earth registry registration.

Step 4: If Google Earth is now open and running, close it. Now you need to make a backup of your registry. Follow this step in the pdf file:

Step 5: Download then run this registry update: Google Earth Registry Patch and say OK to everything. Try Model Maker again.
