How to Disable the Fatal Error in Opera Installer on Windows Startup

If you're using Opera 100.0.4815.30 or a later version, you might have encountered a frustrating issue where the browser displays a fatal error message upon startup. This error occurs when the installer executable is loading, and it can be quite annoying, especially if you're not even planning to install the browser.

The error dialog appears only on Windows Startup, which suggests that there's an issue with the Opera Installer configuration or settings. In this article, we'll explore how to disable this fatal error message and get back to enjoying your browsing experience without interruptions.

To start troubleshooting, let's take a closer look at the error message. When you see the 'Fatal Error upon loading installer executable' dialog box, it provides some line numbers that might seem cryptic. However, these lines are actually related to the operation being completed successfully in different stages of the installation process. The lines mentioned in the error message include:

* In line 178: The specified procedure could not be found.

* In line 273: The operation completed successfully.

* In line 304: The operation completed successfully.

* In line 273: The operation completed successfully (again).

* In line 308: The operation completed successfully.

Despite these lines suggesting that the operations are completing successfully, the fatal error message is still displayed. This implies that there's an underlying issue with the Opera Installer configuration or settings.

To disable this fatal error message and prevent it from appearing on Windows startup, follow these steps:

1. Search for the Task Scheduler in your Start menu or type 'Task Scheduler' in the Run dialog box (Windows key + R).

2. Open the Task Scheduler and navigate to the 'Task Scheduler Library' section.

3. Look for any tasks related to Opera Installer and right-click on them to select 'Disable'.

4. Repeat this process for all Opera-related tasks found in the Task Scheduler.

After disabling these tasks, restart your PC to see if the fatal error message is gone. If you still encounter issues, you can try reinstalling Opera or seeking further assistance from Opera's support team.

In conclusion, the fatal error message displayed by Opera Installer on Windows startup is usually caused by an issue with the installer configuration or settings. By disabling the relevant tasks in the Task Scheduler, you should be able to prevent this error from appearing and enjoy a smooth browsing experience with your Opera browser.
