"Command failed" after converting Citavi fields to text

Cause

The document is too big

In documents with over 300 pages and several thousand references, Word sometimes cannot convert the Citavi fields into text anymore because of the size of the document.

There are three work arounds:

A: If it does not matter if the layout of the page is slightly changed, and if it does not matter if cross-references are not maintained:

Save a COPY of your document in the format DOC. All content control elements are deleted.
Highlight the whole text: CTRL+A.
Remove all field functions in your document: CTRL+Shift+F9.
Delete the index at the beginning of the document and add it again via References > Index.

B: If you need to maintain the exact layout of the page but do not need to maintain cross-references:

Save a COPY of your document in the format DOCX.
In the copy of your document, go to Options > Change menu band
In the new window, on the right hand side, tick the entry "Development tools" in Change menu band: Main register cards
Highlight the whole text: CTRL+A.
Remove all field functions in your document: CTRL+Shift+F9.
Click right on one of the greyed-out fields > Remove content control element.
Delete the index at the beginning of the document and add it again via References > Index.

C: If you need to maintain the exact layout of your document, plus cross-references:

Save a COPY of your document in the format DOCX.
In the copy of your document, go to Options > Change menu band
In the new window, on the right hand side, tick the entry "Development tools" in Change menu band: Main register cards.
Go from one Citavi entry to the next, highlight the reference, and remove the field by clicking CTRL+Shift+F9.
Highlight the whole text: CTRL+A.
Click right on one of the fields > Remove content control element.

The installation of Word is damaged.
