Frequently Asked Questions

Why does Excel say 'Error loading add-ins' during installation?

This error generally occurs due to conflicts with other active add-ins, corrupted Office registry settings, or insufficient file permissions preventing the add-in from registering correctly.

Do my regional settings affect Excel add-in installations?

Generally, regional settings (such as using a Danish semicolon for formula separators) do not cause add-in installation failures. The issue is typically related to software conflicts or configuration bugs.

What should I do if resetting the registry doesn't fix the add-in error?

If renaming the registry key does not resolve the issue, you may need to perform an Online Repair of Microsoft Office through the Windows Control Panel, or contact Microsoft Support directly for further diagnostics.
