我正在尝试将游戏与Windows游戏资源管理器集成。到目前为止，我已经将游戏定义格式XML文件嵌入到我的二进制文件中，而我的实际Inno安装脚本将DLL集成到安装程序中，如下所示：
这就是我现在设法做的事情：
[Files]
Source: GameuxInstallHelper.dll; DestDir: "{tmp}"; Flags: dontcopy
[Code]
const
GIS_NOT_INSTALLED = 1;
GIS_CURRENT_USER = 2;
GIS_ALL_USERS = 3;
// Given a game instance GUID and path to GDF binary, registers game with Game Explorer
procedure AddToGameExplorer( GDFBinPath: PChar; GameInstallPath: PChar; InstallScope : integer; GameGUID : GUID );
external 'AddToGameExplorerA@files:GameuxInstallHelper.dll stdcall';
// Given a game instance GUID, unregisters a game from Game Explorer
function RemoveFromGameExplorer( GameGUID : GUID ) : boolean;
external 'RemoveFromGameExplorer@files:GameuxInstallHelper.dll stdcall';
// Given a path to a GDF binary that has already been registered, returns a game instance GUID
function RetrieveGUIDForApplication( GDFBinPath: PChar; var GameGUID : GUID ) : boolean;
external 'RetrieveGUIDForApplicationA@files:GameuxInstallHelper.dll stdcall';
// Creates a unique game instance GUID
function GenerateGUID( var GameGUID : GUID ) : boolean;
external 'GenerateGUID@files:GameuxInstallHelper.dll stdcall';
// Register with Media Center using the data from a GDF binary
procedure RegisterWithMediaCenter( GDFBinPath : PChar; GameInstallPath : PChar; InstallScope : integer; ExePath : PChar; CommandLineArgs : PChar; UseRegisterMCEApp : boolean );
external 'RegisterWithMediaCenterA@files:GameuxInstallHelper.dll stdcall';
// Unregister with Media Center
procedure UnRegisterWithMediaCenter( GameInstallPath : PChar; InstallScope : integer; strExePath : PChar; UseRegisterMCEApp : boolean );
external 'UnRegisterWithMediaCenterA@files:GameuxInstallHelper.dll stdcall';
// Given a a game instance GUID, creates a task shortcut in the proper location
procedure CreateTask( InstallScope : integer; GameInstanceGUID : GUID; SupportTask : boolean; TaskID : integer; TaskName :PChar; LaunchPath : PChar; CommandLineArgs : PChar );
external 'CreateTaskA@files:GameuxInstallHelper.dll stdcall';
// This removes all the tasks associated with a game instance GUID
// Pass in a valid GameInstance GUID that was passed to AddGame()
procedure RemoveTasks( GameInstanceGUID : GUID );
external 'RemoveTasks@files:GameuxInstallHelper.dll stdcall';
// Creates the registry keys to enable rich saved games. The game still needs to use
// the rich saved game header as defined in the documentation and support loading a
// saved game from the command line.
procedure SetupRichSavedGames( SavedGameExtension : PChar; LaunchPath : PChar; CommandLineToLaunchSavedGame : PChar);
external 'SetupRichSavedGamesA@files:GameuxInstallHelper.dll stdcall';
// Removes the registry keys to enable rich saved games.
procedure RemoveRichSavedGames( SavedGameExtension : PChar);
external 'RemoveRichSavedGamesA@files:GameuxInstallHelper.dll stdcall';
但是，我有两个错误，我无法通过它们：
Unknown type 'GUID'
和
Cannot import dll:C:\Users\my user\AppData\Local\Temp\a random name folder\GameuxInstallHelper.dll
如何解决错误或修改代码？
