What GUI are you trying to use it with?
STOCKFISH 9
You need to use the correct version with your cpu instruction.
BMI2 is for haswell+
Modern is for sandybridge cpus

thank you, sir. i tried bmi2, popcnt and plain stockfish, without success.
You have to open the exe file and then choose the file you want and extract it, have you tried that?
Instead of opening the .exe file I opened the GUI and then selected the .exe in the engine section.
You just need to do some basic troubleshooting. Go to the engine's executable file and double-click on it. If a black console window pops up, then you know that the executable file is good, and the problem lies elsewhere:

If you instead get an error message, then you know there's something wrong with the executable file. (Either it's corrupt, or perhaps a permissions problem.)
It's just a matter of eliminating possible problems until you find the problem.

it is a 'permission' issue. the file shows black console window on double clicking in other computers and not in my computer. please, suggest steps to overcome the problem

Hello .What's difference between ( stockfish_9_x64_popcnt.exe ) and ( stockfish_9_x64.exe ) ?? Which is stronger?

popcnt version should be faster as it is using popcount, a CPU instruction that count and unstack bits on bitboards (a way to code the board using 64bit integers)
This is a very efficient way for the engine to evaluate positions and it is used in several strong engine
