Error in Capacitive Touch Tuning Process

Hi everyone,

When I try to perform capacitive touch tuning with  CapTouch Main / Sensor Tuner RA (QE) on my custom designed hardware, I get an error saying "Not supported launch in background. Please refer to help. Failed to tuning." I am using R7FA2E1 processor on my hardware. If anyone can inform me or give an advice about this situation, I will appreciate it. Thanks a lot.
