Which Cortona3D installer to choose - x32 or x64?


It is recommended to use 64–bit version of any Cortona3D tool on x64–based operating systems. 64bit version of the tool allows working with bigger geometry by utilizing more available RAM on your machine.

64bit installer includes both 32 and 64bit versions of the product. 

The version of your Operating System can easily be checked by rightclicking Computer icon and selecting Properties. "System Type" indicates the version of OS (see screenshot below).
