Problem

You don't see the Adobe Reader and Acrobat Picker.

Cause

The Citavi Picker is only available for the 32bit version of Acrobat, not for the 64bit version of Acrobat. However, the 32bit version is not supported by Acrobat anymore and the Citavi Picker for Acrobat will thus be deprecated. 

Solution

You don't need Acrobat, you can perform the same functions without the program.

1. Add PDF document as reference: From File Explorer, drag the file to the left column of Citavi.

2. Add as local file to the current Citavi reference: From File Explorer, drag the file to the bottom center of the Title tab

All other features present in Acrobat Picker are from a time when PDF files could not be edited and annotated in Citavi. 
It is advantageous to use the integrated PDF viewer, because knowledge items that are extracted from the PDF in Citavi are linked to the exact position in the PDF document, which means that you can jump to the exact location at any time with one click. You can do this even from within Word.

Knowledge items that are picked directly in Acrobat are not linked to the exact location in the PDF document.
