KillProc plug-in is not working in x64 bit machines

I have written following code:

StrCpy $0 "Draw.exe"
KillProc::FindProcesses
${If} $0 > 0
StrCpy $0 "Draw.exe"
KillProc::KillProcesses
${Endif}

this code is working fine on 32 bit machine,
anyone can please suggest what to do for for killing process in x64 bit machine.
