Need help

hi
i’m trying to write an actionscript that will, by pressing abutton, open the windows sound recorder. i wrote this action:
on (release) {
getProperty("%SystemRoot%\System32\sndrec32.exe")
}

and got a massege:
Error Scene=Scene 1, layer=Layer 1, frame=1:Line 2: Wrong number of parameters; getProperty requires exactly 2.
getProperty("%SystemRoot%\System32\sndrec32.exe")
Error Scene=Scene 1, layer=Layer 1, frame=1:Line 3: Unexpected ‘}’ encountered
}
Total ActionScript Errors: 2 Reported Errors: 2

can any body tell me what i did wrong, and what was my mistake?
thanks
