There should be some documentatio/install files under the PSoC Creator install directory related to the CY5677 if you installed the CY5677 dongle kit through the PSoC creator.
The file location would be similar to this: C:\Program Files (x86)\Cypress\CY5672 PRoC BLE RC RDK\1.0\Firmware\
Did you see a mass storage device on your PC as well as a CMSIS-DAP? If so, the KitProg software on the PSoC 5LP is in the "Mass Storage" mode. Please refer following thread.
