Inno setup 使用检查函数时原型无效

我是InnoSetup的新手，因为我正在尝试各种安装程序

我使用Inno script Studio和内置向导创建了我的第一个脚本。到现在为止，一直都还不错。现在，我想让它检测是否安装了.NET4.5，如果没有，则安装它。所以，我浏览了整个网页，在这里我发现了，但是当我复制并粘贴代码到我的脚本中时，我在编译时遇到了以下错误

Compiling [Code] section
Compiler Error!
Line 54: Column 10: Invalid prototype for 'IsDotNetDetected'

我的剧本第54行是这样的

function IsDotNetDetected(version: string; service: cardinal): boolean;

有人知道这个错误是什么意思以及我为什么会得到它吗

以下是我的完整脚本：

#define MyAppName "AVO Log"
#define MyAppVersion "0.1.0.1"

32位系统的.Net 4检查示例

function NET4032(): Boolean;
var
InstallCheck : Cardinal;
begin
  RegQueryDWordValue(HKLM32, 'SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full', 
'Install', InstallCheck);
    if InstallCheck = $1 then
       Result := false
    else
       Result := true;
end;

我的灵能告诉我，你试图将此函数用作

检查：

参数。由于与

check:

参数一起使用的函数必须具有，编译器将失败

尝试使用此存根函数：

function CheckIsDotNetDetected(): boolean;
begin
    result := IsDotNetDetected('v4\Client', 0);
end;

@Gaz83您没有明确提到您正在使用

检查：

参数。这是你在原文章上添加的一个问题，导致了这个问题。@Deanna抱歉，如果这听起来很愚蠢，那你是什么意思？在原始文章中，作者在

InitializeSetup（）

函数中使用了

检查：

。虽然我没有使用该功能，但我仍在运行

检查：

。请参阅

[Run]

下的第一行。。。除非我完全做错了，否则那篇文章的作者将该函数用作签入代码，而不是节条目的参数。好吧，那么我需要对我的脚本做什么才能让它工作呢？我基本上想检查是否安装了.Net 4.5，如果没有安装，然后用我包含的dotNetFx45_Full_x86_x64.exe安装。我想我可能已经找到了答案，只是做了一些工作testing@TLama-你可以纠正我的回答：D.当谈论技能和知识时，我离你有一百万英里远。。。
