1. You must have Google Earth version 4.2 or higher properly installed and be able to successfully login to Google Earth's Server or to your company's geospatial imagery server.
    
2. Your computer must be connected to the Internet before you launch KML Editor.
    
3. The minimum configuration for your PC is:
   • Pentium 3, 500 MHz
   • 128 MB RAM
   • 5 MB free disk space
   • Network speed: 128 kb/s
   • 16 MB 3D-capable graphics card
   • Resolution of 1024x768, 16-bit High Color
   • Windows XP or Windows Vista
      
4. If your operating system is Windows Vista, there are no other requirements.
    
5. Windows XP users will need the Microsoft dotNet Framework version 2.0 or higher installed. The KML Editor installer will guide you for this installation if it is needed. To find out if you have this Framework installed, go to the 'Add/Remove Programs' and look for 'Microsoft .NET Framework' entries in the list of installed software. The Microsoft dotNet Framework is free and can be downloaded from Microsoft's web site. Click here  to go to the download page.

The most likely mode of failure is insufficient video RAM:

• You may get a warning if the graphics card is not able to support Earth.
• This often occurs due to insufficient Video RAM or buggy graphics card drivers.
• The next most likely mode of failure is Internet access speed. Except for the very patient, broadband Internet (Cable, DSL, T1, etc.) is required.
