Fix VBA Automation Error 80004005 When Downloading Excel Files
Question details
The user's VBA macro fails to download an Excel file from a website, resulting in an unspecified automation error instead of saving the file.
- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Automating file downloads from a website using VBA with Internet Explorer and SendKeys.
- Observed behavior
- The target web page opens, but the file fails to download, throwing 'Run-time error -2147467259 (80004005): Automation error—unspecified error.'
Ensure you have a stable internet connection and verify that your antivirus or firewall is not actively blocking automated background downloads.
Fix Browser and Security Blocks
Allow pop-ups and verify security settings aren't blocking the automated download request.
Browsers and security software often block automated download scripts, especially those utilizing legacy Internet Explorer pop-ups.
Go to your browser's settings, locate the site permissions or privacy controls, and add the target URL to the allowed pop-ups list.
Temporarily pause any strict VPN or proxy configurations to ensure they are not dropping the automated download request.
Go to the 'Review' tab in Excel and ensure the worksheet is unprotected, as protected sheets might prevent macros from writing data correctly.
Modernize the VBA Download Code
Replace deprecated Internet Explorer and SendKeys methods with more reliable downloading functions to prevent errors.
Verify Office Bitness Compatibility
Ensure your VBA code is compatible with your current version of Office, especially if you recently upgraded to 64-bit.
Try WPS Office for a Seamless Spreadsheet Experience
If legacy VBA issues and automation errors continue to disrupt your workflow, consider switching to WPS Office. It is a free, lightweight alternative that offers excellent compatibility with Microsoft Office formats, a familiar user interface, and smooth performance.
