修复^(Fix)api-ms-win-crt-runtime-l1-1-0.dll 或 api-ms-win-crt-heap-l1-1-0.dll 缺失

在开始之前，请确保您的Windows已更新 - 因此请检查更新^{(check for updates)} 并确认。此外，运行系统文件检查器 以替换可能损坏的系统文件。重新安装引发此错误的程序也可能会有所帮助。如果没有，请查看以下选项。

1. 修复^(Repair)已安装的Visual C++ 2015 Redistributable包
2. 重新注册DLL文件
3. 通用 C 运行时更新
4. Install Microsoft Visual C++ Redistributable Update
5. Microsoft Visual C++ Redistributable适用于Visual Studio的^{(Visual Studio)}Microsoft Visual C++ Redistributable。

1]修复^(Repair)安装Visual C++ 2015 Redistributable package

损坏的安装或错误的更新可能需要修复Visual C++ 2015 Redistributable包。

如果您已经安装了Visual C++ 2015 Redistributable软件包，但收到错误消息，则可能需要修复该程序。为此，请打开控制面板^{(Control Panel)}并转到“程序^(Programs)和功能”部分。找出Microsoft Visual C++ 2015 Redistributable ( x64 ) [for 64-bit machine] > 右键单击​​它 > 选择更改^{(Change )}按钮 > 单击修复^(Repair)按钮。

如果DLL文件丢失，则从 Internet 下载丢失的 dll 文件^{(missing dll file)}并将其粘贴到特定位置不是实际的解决方案。您可以尝试该方法，但您可能不会从中获得任何积极的结果。

3]通用C运行时更新

^(Download)从Microsoft下载通用 C^{(Universal C Runtime)}运行时 更新^(Update)。安装运行时^(Runtime)组件并重新启动计算机并查看。仅供^(Just)参考，从Windows 10开始，通用 CRT^{(Universal CRT)}是操作系统的一部分。

4]Install Microsoft Visual C++ Redistributable Update

如果这没有帮助，您可能需要在 此处安装来自 Microsoft的^{(Microsoft here)}Microsoft Visual C++ Redistributable Update 。您需要选择Windows的版本，即 64 位或 32 位版本。遵循安装过程并仔细指导以避免安装问题或失败。
