UE 编辑器内 Source Code IDE 没有 Rider

原因：注册表内没有找到

相关代码：

static TArray<FInstallInfo> CollectPathsFromRegistry( const Windows::HKEY RootKey, const FString& RegistryKey)
{
	TArray<FInstallInfo> InstallInfos;
	HKEY Key;
	const LONG Result = RegOpenKeyEx(RootKey, *RegistryKey, 0, KEY_READ, &Key);
	if (Result == ERROR_SUCCESS)
	{
		TArray<FString> Keys;
		if (EnumerateRegistryKeys(Key, Keys))
		{
			for (const FString& key : Keys)
			{
				if (!key.Contains(TEXT("Rider"))) continue;

				HKEY SubKey;
				const LONG SubResult = RegOpenKeyEx(Key, *key, 0, KEY_READ, &SubKey);
				if (SubResult != ERROR_SUCCESS) continue;

				TArray<FString> Values;
				if (!EnumerateRegistryValues(SubKey, Values)) continue;

				for (const auto& Value : Values)
				{
					if (Value != TEXT("InstallLocation")) continue;
					FString InstallLocation;
					if (GetStringRegKey(SubKey, Value, InstallLocation) != ERROR_SUCCESS) continue;
					const FString ExePath = FPaths::Combine(InstallLocation, TEXT("bin"), TEXT("rider64.exe"));
					TOptional<FInstallInfo> InstallInfo = FRiderPathLocator::GetInstallInfoFromRiderPath(ExePath, false);
					if(InstallInfo.IsSet())
						InstallInfos.Add(InstallInfo.GetValue());
				}

			}
		}
	}

	return InstallInfos;
}

添加注册表：（PowerShell 管理员模式），重启编辑器就好了
