Step 5: Launch the Software
Open the CM2SP2 application. If you use an Online/Digital licence, enter the account credentials supplied with your legitimate licence. Dongle users should connect their registered device and follow the official activation or update instructions.
How to Set Up CM2SP2 Drivers
Driver installation is important because the software must communicate with the phone and, where applicable, the Infinity dongle or smart-card reader.
For a reliable setup:
Use the official Infinity driver packages.
Connect the dongle directly to the PC rather than through an unpowered USB hub.
Try another USB port if Windows does not detect the hardware.
Restart Windows after installing or updating drivers.
Check Device Manager for warning symbols or unidentified devices.
Infinity's support instructions provide separate smart-card reader and Virtual COM Port driver resources for supported hardware.
