What are coInst.exe Error Messages?


coInst.exe Runtime Errors

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

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

Some of the most common coInst.exe errors include:

  • coInst.exe - Bad Image.
  • coInst.exe Application Error.
  • coInst.exe could not be found.
  • coInst.exe could not be installed.
  • coInst.exe could not be launched. Class not registered.
  • coInst.exe could not be started.
  • coInst.exe failed to initialize properly.
  • coInst.exe has encountered a problem and needs to close. We are sorry for the inconvenience.
  • coInst.exe is not a valid Win32 application.
  • coInst.exe is not running.
  • Cannot find coInst.exe.
  • Error starting program: coInst.exe.
  • Faulting Application Path: coInst.exe.
  • The file coInst.exe is missing or corrupt.
  • Windows failed to start - coInst.exe.
System Error


The program can’t start because coInst.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 coInst.exe error is key to properly resolving these errors. Although most of these EXE errors affecting coInst.exe will happen during startup, occasionally you will encounter a runtime error while using Norton Identity Safe. This can occur due to poor programming on behalf of Symantec Corporation, conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware. Also, these types of coInst.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.



How to Fix coInst.exe Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your coInst.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 coInst.exe error, please proceed to the Step 2 below.

Step 2: If recently installed Norton Security Premium (or related software), uninstall then try reinstalling Norton Security Premium software.

You can uninstall Norton Security Premium software by following these instructions (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. In the search box, type "Uninstall" and press "ENTER".

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many coInst.exe error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

  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.

If Windows Update failed to resolve the coInst.exe error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.



If Those Steps Fail: Download and Replace Your coInst.exe File (Caution: Advanced)

If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate coInst.exe file version. We maintain a comprehensive database of 100% malware-free coInst.exe files for every applicable version of Norton Security Premium. Please follow the steps below to download and properly replace you file:

  1. Locate your Windows operating system version in the list of below "Download coInst.exe Files".
  2. Click the appropriate "Download Now" button and download your Windows file version.
  3. Copy this file to the appropriate Norton Security Premium folder location:
    Windows 10: C:\Program Files (x86)\Norton Security with Backup\Engine\22.6.0.142\
  4. Restart your computer.

If this final step has failed and you're still encountering the error, you're only remaining option is to do a clean installation of Windows 10.


GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve coInst.exe problems. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. If you are not currently backing up your data, you need to do so immediately.



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


CAUTION : We strongly advise against downloading and copying coInst.exe to your appropriate Windows system directory. Symantec Corporation typically does not release Norton Security Premium 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 coInst.exe and all other EXE files for Norton Security Premium. An incorrectly installed EXE file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
