I test it on 3 different pcs but nrfgo studio didn't work on them and couldn't recognize my board however recently by using JFlashLite (one of the software of my jlink segger) I could program the softdevice on my board (using swd interface), however it program the board randomly I mean sometimes it could program it but sometimes it gives error and really thank you keton for your quick replies I really appreciate it :X

I'm working on Windows 10 64bit without any problems. So it's rather problem with your PC

The solution that I find till now is that to install the nrfGo on a pc with "Windows XP"-32bit operating system

So it seems that the problem is from 64 bit driver

I did it but it didn't solve my problem.... but I find a new solution:

I installed nrfgo for 32 bit system on an old laptop (which its operating system is windows XP) and now it acknowledges my board and I can now program the soft device

so I think the problem is from the driver for 64 bit operating system (so please update the driver and fix this bug)

If that's the case please install latest nRF command line tools and latest J-Link software and then execute nrfjprog -i in commandline with Segger attached. It should display at least one long number. If not this may be driver/connection problem rather than problem with Nordic software.

which model of ARM programmer are you using? Nordic tools work only with Segger J-Link. It's possible to use alternative jtag tool that supports ARM Cortex-M processors and flash softdevice hex using their dedicated software. In fact last year I used STMicro programmer embedded on STM32 Nucleo board and OpenOCD software to work with BLE400 board for educational project. Biggest hurdle is to build experimental version of openocd that supports nRF51 'recover' command as BLE400 chip comes factory locked and needs to be recovered before use. But maybe more recent editions have this in the stable branch.

As for softdevice - it's rather required because it's the piece of software that does all of Bluetooth related stuff.
