EzCad3 software requires the computer with dual-core CPU, 2G or more of memory, 10G or more hard disks, and more than 2 USB ports, and it is suitable for WIN7 64-bit, and WIN10 64-bit. (the software could run on win8-64 bit system also, but need to install many others program, so don’t suggestion win8)
EzCad3 software is an installation-free version. Users only need to copy the file on the installation CD to computer directly. Then run the EzCad3.exe program to use it.
If you do not install the Licenses, you cannot open the software. (This is different from EzCad2: Can not find dog!Soft will work at demo state.)
