Another angle: maybe the user is looking for a way to integrate phone number lookups into Word. There might be other add-ins or services that provide similar functionality now. Suggesting alternatives like Microsoft's own tools or other verified add-ins from the Office Store could be helpful.

Next, the correct steps for downloading software like Infobel usually involve visiting the official website. Since the user mentioned it in Spanish, I should look for the official Infobel Spain site. But wait, maybe the site is in English. Let me check. No, the user might be in Spain, so the site should be in Spanish. The URL should be something like www.infobel.com/es or similar.

The user might be trying to use an outdated version of Office. Office 2013 is quite old, so compatibility could be an issue. If Infobel isn't maintained, installing it on a modern Office version could cause problems.
