Internal DLL Error - TM4C123; No ULINK2 ME/DEVICE found

mySP

I am trying to code on TM4C123GH6PM for the first time on keil. I have installed the necessary package from 'Pack Installer' but I am now facing two issues. I dont have a board, but what i expect is to see a led glowing on PF3 pin of PORTF.

This is my code:

#define SYSCTL_RCGCGPIO_R (*(( volatile unsigned long *)0x400FE608 ) )
#define GPIO_PORTF_DATA_R (*(( volatile unsigned long *)0x40025038 ) )
#define GPIO_PORTF_DIR_R (*(( volatile unsigned long *)0x40025400 ) )
#define GPIO_PORTF_DEN_R (*(( volatile unsigned long *)0x4002551C ) )


int main ( void )
{
SYSCTL_RCGCGPIO_R |= 0x20; // Enable clock for PORTF
GPIO_PORTF_DEN_R = 0x0E; // Enable PORTF Pin1, 2 and 3 as a digital pins
GPIO_PORTF_DIR_R = 0x0E; // Configure ORTF Pin1, 2 and 3 digital output pins

while (1)
{
GPIO_PORTF_DATA_R |= 0x02; // turn on red LED
}
}

Here are the pop up that i get everytime i try to debug:

This is on my build output screen:

I dont have a ULINK2 and nothing is plugged into my USB ports. 

Please help
