Program run in ISIS but not in real hardwar

[ratna555]

Hi,
I have made a simple program (Hello World) it working in simulation (ISIS) but not in real hardware. I hope the problem is come from OSC setting but have no idea about it, i have connected the 8 Mhz XT in proper pin and connected. I am newer in this world request your help regarding that. Incase any additional help required please let me know.

How do you expect help if we can not se what you are doing?
post a screen print of your Configuration settings ,which microcontroller and you schematic then people can help you
we have no glass balll through which we can see what you are doing.

Hi i am using PIC18F4520 with 8 Mhz cristal for clocking, 74595, 4017 and 7seg-CC
it is run fine in Protious but not in real HW
