为了修复 cli_cppuhelper.dll error without downloading anything, you need to configure your environment or project correctly. This file belongs to the LibreOffice or OpenOffice SDK and handles C#/.NET automation. The error usually occurs because Windows cannot find the underlying LibreOffice binaries or there is a 32-bit/64-bit architecture mismatch.

Here are the step-by-step methods to resolve the issue:

Method 1: Add LibreOffice to the System PATH Variable

Right-click your project in the Solution Explorer and select Properties.
让我们去看看. Build 这里是我的房间.
换一个 Platform target 从 Any CPU to either x64 或是 x86 to precisely match the bit version of your installed LibreOffice.

Method 3: Dynamically Set the Path in Code (For Developers)

If you want to ensure the application works on other machines without manually changing system variables, append the path programmatically at startup before calling any LibreOffice functions:

string unoPath = @"C:\Program Files\LibreOffice\program";
Environment.SetEnvironmentVariable("PATH", Environment.GetEnvironmentVariable("PATH") + ";" + unoPath);

Method 4: Run a Built-in System Repair

If the file is part of your local installation but has become corrupted, use the Windows deployment tool to fix system-linked libraries:

它们的类型 cmd 在 Windows 搜索中,右键单击 Command Prompt,并选择 Run as administrator.
