Availability of 64bit of Sierra LandDesigner 3D.There is no 64bit version of the LandDesigner 3D, because it was released a very long time ago. I have checked all the websites, but not a single one of them provides information about the compatibility with 64bit version of Windows. The only thing you can do at this time is install Windows XP through a virtual machine and then run the software virtualized in Windows XP. You can use VirtualBox for this process.
