安装VC可再发行文件和注册VC OCX的InnoSetup脚本会导致"RegSrv32失败，退出代码为0x1". [英] InnoSetup Script installing VC redistributables and registering VC OCX resulting in "RegSrv32 failed with exit code 0x1"

问题描述

我的InnoSetup脚本需要安装VC可再发行文件(vcredist_x86.exe)，而且还需要依赖于Redist软件包注册OCX.我无法在regsrv32调用之前安装软件包，因此在原始系统上，它始终会导致"RegSrv32失败，退出代码0x1"错误(我可以忽略该错误并再次运行安装程序以正确注册OCX ).注册前如何确保已安装redist软件包?

My InnoSetup Script needs to install the VC redistributables (vcredist_x86.exe) but also registers an OCX relying on the redist package. I wasn't able to have the package installed prior to the regsrv32 call, so on a virgin system it always results in a "RegSrv32 failed with exit code 0x1" error (which I could ignore and run the setup again to correctly register the OCX). How can I make sure the redist package is installed before registering?

为方便起见，这是pastebin TLama所引用的代码:

For your convinience, here is the code from pastebin TLama referred me to:

[Setup]
AppName=My Program
AppVersion=1.5
DefaultDirName={pf}\My Program

[Files]
Source: ".\SystemFiles\vcredist_x86.exe"; Flags: dontcopy

[Code]
function IsRuntimeInstalled: Boolean;
begin
  Result := False;
  // here will be a statement that will check whether the runtime is installed
  // and return True if so; see e.g. http://stackoverflow.com/q/11137424/960757
end;

function PrepareToInstall(var NeedsRestart: Boolean): string;
var
  ExitCode: Integer;
begin
  // if the runtime is not already installed
  if not IsRuntimeInstalled then
  begin
    // extract the redist to the temporary folder
    ExtractTemporaryFile('vcredist_x86.exe');
    // run the redist from the temp folder; if that fails, return from this handler the error text
    if not Exec(ExpandConstant('{tmp}\vcredist_x86.exe'), '', '', SW_SHOW, ewWaitUntilTerminated, ExitCode) then
    begin
      // return the error text
      Result := 'Setup failed to install VC++ runtime. Exit code: ' + IntToStr(ExitCode);
      // exit this function; this makes sense only if there are further prerequisites to install; in this
      // particular example it does nothing because the function exits anyway, so it is pointless here
      Exit;
    end;
  end;
end;
