maybe I can help with this link.

Is in German as requested by you.

Formel-Editor

https://support.microsoft.com/de-de/office/formel-editor-6eac7d71-3c74-437b-80d3-c7dea24fdf3f

This font will enable display of Math equations created using Microsoft Equation Editor 3.0.

Install MTEXTRA.TTF (is not supported in the download, unfortunately I cannot send it to you, please download it yourself)

To install this font on a single PC:
1. Locate the MTEXTRA.TTF font file you just downloaded.
2. Right-click the font file and choose Install.

After that visit this Link

Read the instructions carefully in the first link from Microsoft, all details are described there. Hope it was this kind of editor. If not, just ignore it.

PS. The editor is only available in English, but that doesn't mean that it doesn't work with German office versions, so read it carefully.

I wish you a pleasant day.
