Some Aerotech products have installations for 32-bit operating systems and for 64-bit operating systems. The 64-bit installation installs applications that can process larger files and sometimes perform faster. For example, the 64-bit CADFusion application can import larger files and process more shapes than the 32-bit version. You must have a 64-bit operating system to use the 64-bit installation.
Follow these Instructions from Microsoft to determine what type of system you have.
