What are AddInUtil.exe Error Messages?

AddInUtil.exe Runtime Errors

Runtime errors are Windows errors that occur during "runtime". Runtime is pretty self-explanatory; it means that these EXE errors are triggered when AddInUtil.exe is attempted to be loaded either when Windows is starting up, or in some cases already running. Runtime errors are the most common form of EXE error you will encounter using Windows.

In most cases, AddInUtil.exe runtime errors occurring while the program is running will result in the program terminating abnormally. Most of these AddInUtil.exe error messages mean that Windows was either unable to locate this file on startup, or the file is corrupt, resulting in a prematurely-aborted startup process. Generally, Windows will be unable to start without resolving these errors.

Some of the most common AddInUtil.exe errors include:

  • AddInUtil.exe - Bad Image.
  • AddInUtil.exe Application Error.
  • AddInUtil.exe could not be found.

System Error

The program can’t start because AddInUtil.exe is missing from your computer. Try reinstalling the program to fix this problem.

Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

Finding the source of the AddInUtil.exe error is key to properly resolving these errors. Although most of these EXE errors affecting AddInUtil.exe will happen during startup, occasionally you will encounter a runtime error while using Windows 10. This can occur due to poor programming on behalf of Microsoft, conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware. Also, these types of AddInUtil.exe errors can occur if it has been accidentally moved, deleted, or corrupted by a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your AddInUtil.exe issue. These troubleshooting steps are listed in the recommended order of execution.

Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. When you see the search box, type "System Restore" and press "ENTER".
  3. In the search results, find and click System Restore.
  4. Please enter the administrator password (if applicable / prompted).
  5. Follow the steps in the System Restore Wizard to choose a relevant restore point.
  6. Restore your computer to that backup image.

If the Step 1 fails to resolve the AddInUtil.exe error, please proceed to the Step 2 below.

Step 2: Run SFC (System File Checker) to restore the corrupt or missing AddInUtil.exe file.

System File Checker is a utility included with every Windows version that allows you scan and restore corrupted system files. Use the SFC tool to fix missing or corrupt AddInUtil.exe files (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. In the search box, type "cmd" but DO NOT PRESS "ENTER".
  3. Press and hold "CTRL-Shift" on your keyboard while pressing "ENTER".
  4. You'll be prompted with a permission dialog box.

  7. In that black screen, type "sfc /scannow" and hit "ENTER".
  8. SFC will begin scanning for AddInUtil.exe issues and any other system file problems.

  1. Hit the Windows Start button
  2. In the search box, type "Update" and press "ENTER".
  3. In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
  4. If updates are available for download, click "Install Updates".
  5. After the update is completed, restart your PC.

Download AddInUtil.exe Files (Malware-Tested 100% Clean)

CAUTION : We strongly advise against downloading and copying AddInUtil.exe to your appropriate Windows system directory. Microsoft typically does not release Windows EXE files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing AddInUtil.exe and all other EXE files for Windows. An incorrectly installed EXE file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
