优化方案：

取代WinExe用CreateProcess用来启动进程, 执行批处理文件, 同时系统会自动填写TProcessInformation这个结构。

此时程序会自动阻塞到该批处理中，等待批处理句柄的进程结束或超时。这样就能解决压缩损坏问题。

给个实例Demo:

D7代码如下：

unit uMain;interfaceuses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, RzButton, StdCtrls;type TFrmMain = class(TForm)  mmMsg: TMemo;  btnExecute: TRzBitBtn;  btnClear: TRzBitBtn;  procedure MsgDsp(v_Str: string);  procedure btnExecuteClick(Sender: TObject);  procedure btnClearClick(Sender: TObject); private  { Private declarations } public  { Public declarations } end;var FrmMain: TFrmMain;implementation{$R *.dfm}procedure TFrmMain.MsgDsp(v_Str: string);begin mmMsg.Lines.Add('[ admin ] - [' + v_Str + '] - [' + FormatDateTime('YYYY-MM-DD hh:mm:ss zzz', Now()) + ']');end;procedure TFrmMain.btnExecuteClick(Sender: TObject);var sInfo: TStartupInfo; pInfo: TProcessInformation; cmdLine: string; exitCode: Cardinal;begin MsgDsp('初始化参数'); cmdLine := 'C:\Program Files\7-Zip\7zFM.exe'; FillChar(sInfo, sizeof(sInfo), #0); sInfo.cb := SizeOf(sInfo); sInfo.dwFlags := STARTF_USESHOWWINDOW; sInfo.wShowWindow := SW_NORMAL; MsgDsp('参数初始化完成，启动WinExec调试'); //CreateProcess用来启动进程, 进程启动后, 会填写TProcessInformation这个结构， //此时程序阻塞到该句柄中，等待句柄的进程结束或超时 if not CreateProcess(nil, pchar(cmdLine), nil, nil, false, CREATE_NEW_CONSOLE or NORMAL_PRIORITY_CLASS, nil, nil, sInfo, pInfo) then begin  MsgDsp('WinExec调试失败！');  MessageBox(Application.handle, '指定程序启动失败!', '错误', MB_OK or MB_ICONSTOP); end else begin  //等待指定句柄的进程结束或超时  WaitForSingleObject(pInfo.hProcess, INFINITE);  GetExitCodeProcess(pInfo.hProcess, exitCode);  MsgDsp('WinExec调试成功！'); end;end;procedure TFrmMain.btnClearClick(Sender: TObject);begin  mmMsg.Clear;end;end.
