FlashScan V2 users require both V7 and V8 software. The V8 software manages reading/flashing/logging for your 2011 Cummins and that software also manages the firmware that controls your FlashScan V2. V7 software manages tune editing.
You will find the latest public pre-release software for both V7 and V8 here:

Once you have downloaded and installed both softwares, open V8 Scan and Tune to update your firmware (and if necessary your bootblock). Instructions can be found here
