While performing a copy/paste function from ChemDraw into Word for Mac 2016, the result is a SMILES string, and not a structure. How to fix this?
The reason is a change in the way Microsoft decides what to paste from the clipboard. The way SMILES was registered as textual data meant that MS Office preferred to paste it instead of the PDF image from the document. We worked around this by removing the problematic registration from the SMILES type. The problem is that if there are multiple versions of ChemDraw installed on the system, the old registration will conflict with the newer, cleaned up version. Users need to remove old versions entirely from their system and clean up there launch services database using a command line to do so.
The following command line can be used to remove an old version:
/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user
