How to Fix microsoft.visualstudio.tools.office.runtime.v10.0.dll Errors Without Downloading

You do not need to download this DLL file from sketchy third-party websites. The safe and correct way to fix this error is by repairing or reinstalling the official Microsoft software that includes it.

Method 1: Repair or Reinstall Visual Studio Tools for Office (VSTO) Runtime

This DLL is a core component of the VSTO Runtime. Repairing it will restore the missing file.

Press Windows Key + R, type appwiz.cpl, and press Enter.
Scroll through the list to find Microsoft Visual Studio 2010 Tools for Office Runtime.
Right-click it and select Change or Repair.
Choose the Repair option and follow the on-screen prompts.
Restart your computer.

Note: If it is not listed, or if repairing fails, you can reinstall it safely by running the installer already bundled inside your Microsoft Office installation folder, or by enabling it via Visual Studio Installer if you are a developer.

Method 2: Repair Microsoft Office

Since this error usually triggers when launching Office Add-ins (like in Excel or Word), repairing Office will often fix the broken dependencies.

Open Settings (Windows Key + I) and go to Apps > Installed apps.
Find your Microsoft Office or Microsoft 365 installation.
Click the three dots (...) next to it and select Modify.
Select Quick Repair first (takes a few minutes).
If the error persists, repeat the steps and choose Online Repair.

Method 3: Run System File Checker (SFC)

If the DLL file or its registration registry entries are corrupted, Windows can self-heal using built-in deployment tools.

Type cmd in the Windows start menu search bar.
Right-click Command Prompt and select Run as administrator.
Type the following command and press Enter: sfc /scannow
Wait for the scan to hit 100%. If it finds corrupt files, Windows will automatically replace them.
Restart your PC.
