阅读13分钟DirectX 可以通过 Windows 更新、官方运行库安装程序、显卡驱动更新三个途径解决，多数报错并非硬件损坏，而是系统环境缺失组件或驱动版本过旧造成的，不必急着重装系统或送修。
以下三个方法由易到难，按 Windows 更新 → 官方运行库补全 → 显卡驱动与系统升级的顺序逐一排查，修好即停；以下方法在 Windows 10/11 实测可用。
适用系统：Windows 10/11；最后更新：2026-06-22。
DirectX 更新安装是什么情况
DirectX 是微软内置的多媒体接口技术，负责图形渲染、音频输出和游戏输入。当游戏启动时弹出「无法启动此程序，因为计算机丢失 d3dx9_43.dll」或「DXGI.DLL 未找到」，通常意味着系统缺少对应版本的 DirectX 运行库组件。Windows 10/11 内置 DirectX 12，但 DirectX 9/10/11 的旧版 DLL（如 `d3dx9_*.dll`、`d3d11.dll`）并非随系统自动安装，许多旧游戏和软件仍依赖这些组件。

先用 Win+R 输入 dxdiag 回车，在「DirectX 诊断工具」查看当前版本和显卡功能级别，再对症处理，能省去大量盲目重装。
方法一 通过 Windows 更新升级 DirectX 版本
Windows 10/11 的 DirectX 更新随系统补丁一起推送，没有独立安装包；如果当前 DirectX 版本低于预期，运行系统更新是最稳妥的第一步。
操作步骤
- 按
Win+R输入dxdiag回车，在弹出的诊断工具「系统」选项卡确认当前 DirectX 版本（Win10/11 正常应显示 DirectX 12）。 - 点击「开始」→「设置」→「更新和安全」（Win11 为「Windows 更新」）。
- 点击「检查更新」，等待系统下载并安装所有待更新补丁（含最新 DirectX 组件）。
- 更新完成后重启电脑，再次运行
dxdiag确认版本已更新。
Windows 更新流程将自动下载并安装 DirectX 相关补丁，完成后 dxdiag 显示版本应为 DirectX 12。

方法二 下载安装 DirectX 运行库补全旧版组件
即便系统已是 DirectX 12，许多游戏仍需 DirectX 9/10/11 的旧版 DLL 文件；通过微软官方 DirectX End-User Runtime 安装程序可以一次性补全这些缺失组件。
操作步骤
- 在浏览器搜索「Microsoft DirectX End-User Runtime」，进入微软官方下载页面（microsoft.com），下载 `dxwebsetup.exe`（在线安装程序，约 300 KB）或离线安装包（约 96 MB）。
- 以管理员身份运行安装程序，安装前暂时关闭杀毒软件以防拦截；点击「下一步」接受许可协议。
- 程序自动检测系统缺失的 DirectX 组件（如 `d3dx9_24.dll` 至 `d3dx9_43.dll`），联网版会实时下载，离线版直接从安装包读取，无需网络。
- 安装完成后重启电脑，再次启动游戏测试，确认 DLL 报错是否消失。
若安装失败，常见原因是系统权限不足或运行库残留冲突；可先在命令提示符（管理员）运行 sfc /scannow 修复系统文件，再重试安装。

方法三 排查显卡驱动与系统版本解决不支持 DirectX 12 的问题
如果 dxdiag 的「显示」选项卡「功能级别」显示低于 12.x，或游戏提示「系统不支持 DirectX 12」，需从硬件支持、系统版本、驱动版本三个方向逐一排查。
操作步骤
- 运行
dxdiag，切到「显示」选项卡，查看「功能级别」；低于 12.0 说明显卡不支持 DX12（需更换支持 DX12 的显卡，如 NVIDIA GTX 900 系列及以上、AMD RX 400 系列及以上）。 - 确认系统版本：按
Win+R输入winver，DirectX 12 仅支持 Windows 10 及以上；如仍在 Windows 7/8，需升级至 Windows 10/11。 - 在设备管理器（
Win+X→「设备管理器」）中展开「显示适配器」，右键显卡→「更新驱动程序」；或前往 NVIDIA/AMD/Intel 官网按显卡型号下载最新驱动手动安装。 - 驱动更新前如需彻底清除旧驱动，可下载 DDU（Display Driver Uninstaller），在安全模式下卸载后再安装新驱动，避免残留冲突。
- 若游戏仍崩溃，可在 Steam 游戏属性的「启动选项」中加入
-dx11参数，或在游戏图形设置切换为 DirectX 11 或 Vulkan。
完成驱动更新后重启电脑，再次运行 dxdiag 确认功能级别已提升至 12.x；游戏若仍不支持，优先尝试切换 -dx11 启动参数。

常见问题
directx怎么更新到最新版本？
Windows 10/11 上没有单独的 DirectX 安装包，打开「设置→Windows 更新→检查更新」让系统自动下载即可；更新完成后用 dxdiag 确认版本为 DirectX 12。
系统不支持directx12怎么办？
先在 dxdiag 的「显示」选项卡查看「功能级别」；低于 12.0 是显卡硬件不支持，需更换显卡；功能级别正常但游戏报错，则优先更新显卡驱动，或在游戏启动参数加 -dx11 切换版本。
directx运行库下载安装后游戏还是报错怎么办？
报错的 DLL 可能属于 VC++ 运行库而非 DirectX；查看报错文件名，若是 msvcp140.dll、vcruntime140.dll，则需额外安装 Microsoft Visual C++ Redistributable。也可用软领DLL系统修复的运行库修复功能一次性扫描补全。
dxdiag显示directx12但游戏提示需要directx11？
这是游戏兼容性问题而非系统缺失；在游戏图形设置中将渲染 API 切换为 DirectX 11，或在 Steam 启动参数里添加 -dx11，通常能解决此类崩溃。
安装directx运行库提示"已是最新版本"但问题未解决？
Win10/11 系统自带核心 DirectX 12，提示"最新版本"是正常的；但旧版 DLL 组件（d3dx9_*.dll）需要单独的 DirectX End-User Runtime 来补全，两者不同；按本文方法二下载 dxwebsetup.exe 安装即可。
