I'm using Inno Setup Compiler 4.1.7 to create setup disk

but in [Icons]
Name: "{group}\Check Key Disk"; Filename: "{app}\cclook.exe"; WorkingDir: "{app}"
will only run the program.
If I want to run cclook.exe with parameter then how ? something like "c:\myfolder\cclook.exe" A:\ in target of the icon
