hey guys the problem is caused by .exe registration entry in registry here the solution:
1-Enter Safe Mode
2-run regedit ( as administrator)
3-Go to
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\exefile\shell\ open\command

and look at the default value

4- It should be like "%1" %*

if u find that it's like "%1" %*" or "%1" %" or "%1" %

correct it to "%1" %*

5- Restart the pc and everything will return to the normal !
