🛠 How to Fix “MSVCR100.DLL Was Not Found” Error in BFT Best Flash Tool

Are you trying to open **BFT Best Flash Tool** and seeing the error:

“The program can't start because MSVCR100.DLL was not found on your computer.”

Don’t worry! This is a common issue on Windows computers (both 32-bit and 64-bit). In this post, I will show you a **step-by-step guide** to fix it easily. After following this guide, you will be able to open the tool without any errors.

🔍 Why This Error Occurs

The error appears because **MSVCR100.DLL**, a critical file of **Microsoft Visual C++ 2010 Redistributable**, is either missing or corrupted on your system. Without this DLL file, **BFT Best Flash Tool** cannot start.

Common causes:

  • The Visual C++ 2010 package is not installed.
  • Windows update removed or replaced the DLL.
  • Antivirus mistakenly quarantined the file.

🧰 Requirements Before Fix

Before starting, make sure you have:

  1. A **Windows computer** (32-bit or 64-bit)
  2. Internet connection to download required files
  3. **WinRAR or 7-Zip** to extract the DLL pack
  4. Access to your **BFT Best Flash Tool installation folder**

🔧 Step 1: Install Microsoft Visual C++ 2010 Redistributable

This is the official and primary solution from Microsoft. Installing this package automatically places the **MSVCR100.DLL** file where Windows needs it.

  1. Open the official Microsoft download page:
    👉 Microsoft Visual C++ 2010 Redistributable
  2. On the page:
  • **64-bit Windows:** Download **both** vcredist_x86.exe and vcredist_x64.exe
  • **32-bit Windows:** Download **only** vcredist_x86.exe
  1. Once downloaded, run the installers and follow the on-screen instructions.

Note: Installing Visual C++ 2010 ensures that all required DLL files, including **MSVCR100.DLL**, are correctly placed in your system.

🔧 Step 2: Download Missing MSVCR100.DLL Manually

If Step 1 does not resolve the issue, you need to download and place the file manually.

👉 Download msvcr100.dll (RAR file)

This ensures both 32-bit and 64-bit applications can access the DLL file correctly.
