Yes it does. You want urgent help but have provided next to no details.

Please post all the output from the programmer.

Did you build the JDM?

Are you using a USB to RS232 converter?

Have you programmed any other PIC with this programmer?

Maybe your PIC does not work! Have you tried another pic16f877?
which software are you using?

 

I test two PIC which is did't work at all

Stupid question, but did you select the F877 programming option and set the proper oscillation settings?
