 Why Does This DLL Missing Error Happen?

When you install a fresh copy of Windows, the system lacks several legacy C++ runtime dynamic link libraries (`.dll` files). Because BFT Flash Tool relies heavily on Microsoft Visual C++ dependencies to initialize its interface and drivers, it throws an error if `msvcr100.dll` or `msvcp100.dll` is missing from the working path.

Step 3: Install Visual C++ Runtimes (100% Final Solution)

If your tool still fails to open after Step 2, don't worry. Your Windows OS is missing a broader set of C++ system libraries.

1. Go back to your extracted fix folder.

2. Open the subfolder named **`Visual-C-Runtimes-Allin-One`**.

3. Locate the file named `install_all` (or `install_all.bat`).

4. Right-click it and select **Run as Administrator**.

5. Wait a few moments while the script automatically installs all required Microsoft Visual C++ Redistributable packages onto your system.

Once completed, reopen your tool. **This guarantees a 99% fix for the startup error.**
