What was the original .exe file written for ?

Like I said in answers to your previous questions, why mess around ? Just use P89V51 series parts and program directly with the serial port !

Mine doesn't matter, WHAT DID THE ORIGINAL PROGRAM RUN ON ?????

The one you download from http://www.ikalogic.com/in-system-programming-isp-for-atmel-chips/
Is it FOR Win7, XP or 98 ?

i used various softwares like ISP programmer, proload4.1, atmel isp etc.. but mostly doesnt works due to Win7 and the program crashes...

Moral: Don't use Win7, except in compatibility mode.
