如何从注册表中获取 Office 的安装目录以进行 Inno 安装程序

Question

我正在为Microsoft Office创建一个安装程序，专门用于2007 - 2013版本。它只是复制了两个Office目录中的一些文件。我的Windows是64位的，但是我想为x64和x86体系结构创建一个安装程序。

因此，我编写了以下代码，试图从Windows注册表中获取Office的安装路径。而且，对于每个版本的Office（2007-2013），它都采用安装路径并附加我所需的其余路径。这是我想要的结果。

[Code]
function GetHKLM() : Integer;

begin
 if IsWin64 then
  begin
    Result := HKLM64;
  end
  else
  begin
    Result := HKEY_LOCAL_MACHINE;
  end;
end;

function officeInstallDir(Param: string): string;
// This function takes the type of desired directory,
// verify the version of Office and returns the correct
// directory for style or bibform.

var
    styleFolder, bibformFolder : string;

begin
    // It verifies the Office version through the registry's subkey and it sets the correct Office's path.
    if RegKeyExists(GetHKLM(), '\SOFTWARE\Microsoft\Office\15.0') then begin
        styleFolder     := '{userappdata}\Roaming\Microsoft\Bibliography\Style';
        RegQueryStringValue(GetHKLM(), '\SOFTWARE\Microsoft\Office\15.0\Common', 'InstallRoot', bibformFolder);
        bibformFolder   := bibformFolder + '\1046\Bibliography';
    end else begin
        if RegKeyExists(GetHKLM(), '\SOFTWARE\Microsoft\Office\14.0') then begin
          RegQueryStringValue(GetHKLM(), '\SOFTWARE\Microsoft\Office\14.0\Common', 'InstallRoot', styleFolder);
          styleFolder       := styleFolder + 'Bibliography\Style';
          bibformFolder := styleFolder + '1046\Bibliography';
        end else begin
          if RegKeyExists(GetHKLM(), '\SOFTWARE\Microsoft\Office\12.0') then begin
            RegQueryStringValue(GetHKLM(), '\SOFTWARE\Microsoft\Office\12.0\Common', 'InstallRoot', styleFolder);
            styleFolder     := styleFolder + 'Bibliography\Style';
            bibformFolder   := styleFolder + '1046\Bibliography';
          end
        end;
    end;

    // Set the result according Param passed (the first or second type of path).
    if Param = 'style' then begin
        result := styleFolder;
    end else begin
        result := bibformFolder;
    end;

end;

对于其中一个路径，我尝试在Inno Setup中设置文件的安装路径(DestDir ),如下所示:

[Files]
Source: "E:\Google Drive\Informática\Bibword\Bibword Estilos\*"; DestDir: "{code:officeInstallDir|style}"; Flags: ignoreversion
Source: "E:\Google Drive\Informática\Bibword\Bibword file\BIBFORM.xml"; DestDir: "{code:officeInstallDir|bibform}"; Flags: ignoreversion

但是如果我传递参数的样式或bibform，函数officeInstallDir应该可以帮助我为每一行设置正确的路径。但是RegKeyExist或RegQueryStringValue找不到注册表的子项。我甚至尝试使用GetHKLM（）函数，因为64位节点有问题，但没有成功。

有人会帮助我吗？

在你的帮助下，这是我解决问题的最终方案。我注意到我在第64行（DestDir参数）中漏掉了最后一个双引号。

谢谢大家，伙计们！

当在64位系统上运行32位安装程序时，Inno会自动将< code>HKLM扩展为< code > HKEY _ LOCAL _ MACHINE \ SOFTWARE \ wow 6432 node ，这意味着您不必在此操作，除非安装了64位office，它可能会在64位注册表分支中保存他的注册表信息。但是，如果< code>IsWin64 = true，您可以对< code>HKLM64进行额外的检查。尽管您必须将它作为< code>String而不是< code>Integer来传递，就像您在代码中所做的那样。

我会这样称呼它（但我不太明白您的代码的最后一部分，因此我刚刚粘贴了它）：

[Code]
function officeInstallDir(Param: string): string;
var
    styleFolder, bibformFolder : string;

begin
    if RegKeyExists(HKEY_LOCAL_MACHINE, 'SOFTWARE\Microsoft\Office\15.0\Common\InstallRoot') then 
    begin
        RegQueryStringValue(HKEY_LOCAL_MACHINE, 'SOFTWARE\Microsoft\Office\15.0\Common\InstallRoot', 'Path', bibformFolder);
        styleFolder := ExpandConstant('{userappdata}') + '\Roaming\Microsoft\Bibliography\Style';
        bibformFolder := bibformFolder + '\1046\Bibliography';
    end 
    else begin
        if RegKeyExists(HKEY_LOCAL_MACHINE, 'SOFTWARE\Microsoft\Office\14.0\Common\InstallRoot') then 
        begin
          RegQueryStringValue(HKEY_LOCAL_MACHINE, 'SOFTWARE\Microsoft\Office\14.0\Common\InstallRoot', 'Path', styleFolder);
          styleFolder := styleFolder + 'Bibliography\Style';
          bibformFolder := styleFolder + '1046\Bibliography';
        end 
        else begin
          if RegKeyExists(HKEY_LOCAL_MACHINE, 'SOFTWARE\Microsoft\Office\12.0\Common\InstallRoot') then 
          begin
            RegQueryStringValue(HKEY_LOCAL_MACHINE, 'SOFTWARE\Microsoft\Office\12.0\Common\InstallRoot', 'Path', styleFolder);
            styleFolder := styleFolder + 'Bibliography\Style';
            bibformFolder := styleFolder + '1046\Bibliography';
          end;
        end;
    end;


    // I quite don't get this part here:
    if Param = 'style' then 
    begin
        result := styleFolder;
    end 
    else begin
        result := bibformFolder;
    end;

end;
