Inno Setup如何自动替换安装路径中的特殊字符？

修改后的代码 #

[Setup]
DefaultDirName={code:GetInstallationPath}

[Code]
var
  InstallationPath: string;

function GetInstallationPath(Param: string): string;
begin
  { Detected path is cached, as this gets called multiple times }
  if InstallationPath = '' then
  begin
    if RegQueryStringValue(
         HKLM64, 'SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Steam App 1580780',
         'InstallLocation', InstallationPath) then
    begin
      { 替换路径中的错误字符 }
      InstallationPath := StringReplace(InstallationPath, 'Σ', 'Σ', [rfReplaceAll]);
      Log('Detected and corrected Steam installation: ' + InstallationPath);
    end
      else
    begin
      InstallationPath := 'C:\games';
      Log('No installation detected, using the default path: ' + InstallationPath);
    end;
  end;
  Result := InstallationPath;
end;

关键修改说明 #

• 在成功读取注册表中的安装路径后，调用Inno Setup内置的StringReplace函数，将路径中的错误字符Σ全局替换为正确的Σ
• 更新日志输出内容，明确记录路径已修正的操作
