Can not kill process InnoSetup

问题

Trying to kill process via InnoSetup installer. But it still shows an error that the processes are running.

I use this.

[Files]
Source: Files\CefSharp.BrowserSubprocess.exe; DestDir: {app}; Flags: overwritereadonly ignoreversion uninsremovereadonly; BeforeInstall: TaskKill('CefSharp.BrowserSubprocess.exe')

[Code]
procedure TaskKill(fileName: String);
var
    ResultCode: Integer;
begin
    Exec(ExpandConstant('{sys}/taskkill.exe'), '/f /im ' + '"' + fileName + '"', ExpandConstant('{sys}'), SW_HIDE, ewWaitUntilTerminated, ResultCode);
end;

or

[Code]
procedure TaskKill(fileName: String);
var
    ResultCode: Integer;
begin
    Exec(ExpandConstant('taskkill.exe'), '/f /im ' + '"' + fileName + '"', '', SW_HIDE, ewWaitUntilTerminated, ResultCode);
end;

Please help
