Automation errors can be caused by various factors, and it's not uncommon for issues to arise after updates or changes in the software environment. Here are some steps you can take to troubleshoot and resolve the Automation error:

  1. Check for Windows and Office Updates:
    • Ensure that your Windows operating system and Microsoft Office applications are up to date. Sometimes, updating to the latest versions can resolve compatibility issues.
  2. Review Recent Changes:
    • Identify any recent changes or updates made to your system, Excel, or VBA code. This could include Windows updates, Office updates, or changes to your VBA code.
  3. Compile VBA Code:
    • Open the VBA editor (Alt + F11), go to Debug > Compile VBAProject. This will identify any syntax errors in your code. Fix any issues reported in the compilation process.
  4. Check References:
    • In the VBA editor, go to Tools > References. Make sure that all the required references are selected and that none are marked as "MISSING." If there are missing references, unselect them and then reselect the correct ones.
  5. Reset VBA Environment:
    • Close Excel and restart it. Open the VBA editor and compile your code again. Sometimes, restarting the application can resolve temporary issues.
  6. Test Code on Another Machine:
    • If possible, test your VBA code on another machine with a similar configuration. This can help determine if the issue is specific to your environment.
  7. Review Code for Changes:
    • Carefully review the VBA code that is causing the Automation error. Ensure that there are no undeclared variables, and check for any changes that might have introduced errors.
  8. Reinstall Office:
    • As a last resort, consider reinstalling Microsoft Office. This can help ensure that the installation is not corrupted.

Keep in mind that debugging VBA issues can be challenging, and it may require a combination of the above steps. Always make sure to back up your files before making significant changes to your environment. The text was created with the help of AI.

 

Otherwise you would have to have the VBA code and/or the VBA file (without sensitive data) to be able to say more precisely.
