This article will guide you through the steps to resolve this error and get your software running smoothly again. **Understanding QuickBooks Update Error 404** QuickBooks Update Error 404 usually appears when the software fails to access the Intuit servers, causing the update process to halt. This can be due to various reasons such as internet connectivity issues, incorrect configuration settings, or problems with the Intuit server itself. The error message may read something like “Error 404: Page Not Found,” indicating that the URL requested by QuickBooks is unavailable or incorrect. **Common Causes of QuickBooks Update Error 404** Internet Connection Issues: A poor or unstable internet connection can prevent QuickBooks from accessing the update servers. Incorrect URL: Sometimes, QuickBooks may be directed to an incorrect or outdated web address. Firewall or Security Software: Overly restrictive firewall or security settings can block QuickBooks from accessing the internet. Browser Settings: Issues with your default browser settings can also interfere with QuickBooks' ability to connect to the server. Corrupted QuickBooks Installation: If the QuickBooks installation files are corrupted or incomplete, it can cause update errors. **Steps to Fix QuickBooks Update Error 404** 1. Check Your Internet Connection Ensure that your internet connection is stable and working correctly. You can do this by trying to access other websites or running a speed test. If your internet connection is unstable, contact your internet service provider to resolve the issue. 2. Verify the URL Ensure that the URL being used by QuickBooks to connect to the Intuit server is correct. Sometimes, an incorrect URL can cause the 404 error. This usually requires checking with Intuit support for the correct web addresses. 3. Adjust Firewall and Security Settings Firewalls and security software can sometimes block QuickBooks from accessing the internet. To resolve this, you can: Add QuickBooks to the Firewall Exceptions List: Go to your firewall settings and add QuickBooks and its components to the list of exceptions. Temporarily Disable Security Software: Disable your antivirus or security software temporarily and try updating QuickBooks again. If this resolves the issue, you may need to configure the software to allow QuickBooks access. 4. Configure Internet Explorer Settings QuickBooks relies on Internet Explorer to access the internet, even if it is not your default browser.
