5. Checking for Windows Updates

Windows Updates often contain fixes for some bugs and glitches but they are also notorious for giving way to new issues on people’s computers. However, in this step, we will be checking for any updates for your Operating system because Microsoft often patches any issues that come from their updates. In order to do that, follow the guide below.

  1. Press “Windows’ + “I” to open Windows settings.
  2. In the settings, click on the “Updates and Security” option and from the left side, select the “Windows Update” option.
    Open Windows Settings and Click Update & Security To Check For Updates

    Check For Updates in Windows Update
  4. After the update check is complete, click on the “Download” button to trigger the downloading and installation of new updates on your computer.
  5. After these updates have been installed, check to see if doing so has fixed the issue on your computer.

6. Restoring Computer

If you have just started getting this issue, it might be getting triggered due to a faulty driver installation or even due to a rogue application that you might’ve installed on your computer recently. Therefore, in this step, we will be reverting the state of the computer to an earlier date and hopefully, this should get our issue fixed if it was due to the above-stated reasons. In order to do this:

  1. Press “Windows” + “R” to open the Run prompt.
  2. Type in “rstrui” and press “Enter” to open the restore management window.
    Run dialog: rstrui
    Run dialog: rstrui
  3. Click on “Next” and check the “Show more Restore Points” option.
  4. Select a restore point from the list that is before the date on which this issue started occurring.
  5. Click on “Next” again and follow the on-screen instructions to revert everything back to the selected date.
  6. After the restore is completed, check to see if the issue still persists.

7. Enable Firewall

It is possible in some cases, that the error is being triggered because the application is suspicious or at least if it has been marked suspicious and the Windows Firewall isn’t running on your computer to validate this suspicious. Therefore, in this step, we will be making sure that the Windows Firewall is enabled in order to get rid of this error. For that:

  1. Press “Windows” + “R” to open the Run prompt.
  2. Type in “Control Panel” and press “Enter” to launch the classical Control Panel interface.
    Typing Control Panel in Run to Open Control Panel
  3. In the Control Panel, click on the “View By:” option and select the “Large Icons” button.

  6. After making this selection, save your changes and close out of the Window.
  7. After doing so, check to see if the issue still persists.

8. Run SFC Scan

In some situations, you might’ve installed a bad driver on your computer or at some point, due to a storage failure, some system files or drivers might’ve been corrupted. Therefore, in this step, we will be running a complete system scan to identify any drivers that are missing signatures or to fix any abnormalities in the system files. For that:

  1. Press “Windows’ + “R’ to open the Run prompt.
  2. Type in “cmd” and then press “Shift’ + “Ctrl” + “Enter” to provide admin permissions.Running the Command Prompt

    sfc /scannow
  4. Let the computer scan for any broken or corrupted items and it should automatically replace them with working ones.
  5. Check to see if doing so fixes the error message.

9. Disabling Data Execution Prevention

Data Execution Prevention is a program that prevents certain programs or executables from being able to run on your computer because it suspects that they might be viruses. Due to this prevention, sometimes, as a false alarm, legit applications might also face issues while trying to run on your computer. Therefore, in this step, we will be disabling this setting from the system configuration panel. For that:

  1. Press ‘Windows’ + “R’ to open the Run prompt.
  2. Type in “Control Panel” and press “Enter” to launch the classical control panel interface.
    Accessing the Classic Control Panel interface
  3. Inside the Control Panel, click on the “View By:” icon and then select the “Large Icons” option.
  4. After selecting Large Icons, select the “System” option.

  7. In the advanced tab, click on the “Settings” option under the “Performance” heading.
    Select Settings
    Advanced Performance Settings
  8. On the next window that opens up, click on the “Data Execution Prevention” tab, and then select the “Turn on DEP for all programs except those I Select” option.
  9. After that, click on the “Add” option and point to the executable of the application that you are facing issues with.
  10. This way, that application will no longer come under the jurisdiction of the DEP program.
  11. Check to see if doing so has fixed the issue.

If the above process is unable to fix the issue, it might be because the executable isn’t the only one being affected by the DEP program. Sometimes the DEP might actually be preventing a herd of executables from being run on the computer and to counter this we will be disabling DEP completely.

Disabling DEP completely cannot be done through any Windows setting and it needs to be done manually through the command prompt. Remember to take this step as a last resort because this can in some cases makes your computer more vulnerable to viruses and malware attacks. In order to disable DEP through the command prompt:

  1. Press “Windows” + “R’ to open the Run prompt.
  2. Inside the Run prompt, type in “cmd” and then press “Shift” + “Ctrl” + “Enter” to launch in admin mode.
    Running the Command Prompt
  3. Inside the command prompt, type in the following command and press “Enter” to execute it on your computer.
    bcdedit.exe /set {current} nx AlwaysOff
  4. Once the command has been executed, run the application that you want to and check to see if the error message still persists.

10. Disable Firewall and Windows Defender

In some situations, the executable that you want to run on the computer might actually be blocked by the Firewall and it would not be able to make contact with its servers this way. Therefore, we will have to allow the executable in our Firewall for both public and private networks which should get it working if the Firewall is preventing it.

In addition to that, sometimes the Windows Defender might prevent the application from running on your computer because its local files might be suspicious and not properly signed. This can be due to a false alarm as well so we will be disabling the Windows Defender for the application as well by adding an exclusion. In order to do that:

  1. Press “Windows” + “R” to launch the Run prompt.
  2. Type in “Control Panel” and press “Enter” to launch the classical control panel interface.
    Accessing the Classic Control Panel interface
  3. Click on the “View by:” button, select “Large Icons” and then click on the Windows Defender Firewall option.
  4. Select the “Allow an app or feature through the Firewall” button on the left pane and then click on the “Change Settings” button and accept the prompt.
    Click on Allow an app or feature through Windows Defender Firewall
    Click on Allow an app or feature through Windows Defender Firewall
  5. From here, make sure that you check both the “Public” and the “Private” options for the application and its entries.
  6. Save your changes and exit out of the window.
  7. After that, press “Windows” + “I” to launch the settings and click on the “Update and Security” option.

  13. Check and see if doing so has fixed the error message.

11. Reinstall Firefox

If you are getting this error while trying to launch Firefox, it might be occurring because the applications haven’t been installed properly on your computer. Therefore, in this step, we will be launching the app management window and uninstalling Firefox after which we will reinstall it completely by downloading it from the Firefox website. For that:

  1. Press “Windows” + “R” to open the Run prompt.
  2. Type in “appwiz.cpl” and press “Enter” to open the app management window.
    Typing in “appwiz.cpl” in the Run prompt
  3. In the app management window, scroll down and right-click on the “Firefox” application.
  4. Select “Uninstall” from the list and then follow the on-screen instructions to remove the software from your computer.
  5. Repeat this step for all instances and bundled applications of the software installed on your computer.

Microsoft Security Scanner is an additional tool that you can use to test the system for any further viruses and malware because sometimes the default tool isn’t able to perform the scan properly. Therefore, in this step, if the issue still hasn’t been resolved, we will be using the Microsoft Security Scanner to further make sure for any issues.

  1. Launch your browser and download the Microsoft Security Scanner from here.
  2. After downloading the executable, run it on your computer and let it install.
  3. Accept the License Agreement terms and click on “Next”.
