DC Proof 2.0 is a PC-based program that makes use of components of the Microsoft Edge web browser. MS Edge needs only to be installed on your computer. It does not need to be your default browser, or to be running or active at any time. Mac or Linux users will also need a Windows emulator (or the equivalent) installed on their computer.
Note: It is not usually necessary to uninstall any older versions before downloading and installing the latest update
