MS Excel: Error when compiling project or library not found

The error message “Error when compiling project or library not found” I had today, She was at one point, to the a variable not previously with Dim were been initialized. There stopped running when my Excel for MAC with the error message:

Fehler beim Kompilieren Projekt oder Bibliothek nicht gefunden

The cause was actually, that a Windows Library was not available, After the reference was removed, everything went back.

Visual Basic Editor-> Extras-> References

There, remove the tick with “DOES NOT EXIST”:
