1. Check if the file association is correct. You can check the default file association here. https://www.lifewire.com/how-to-change-file-associations-in-windows-2624477

2. If the file association is already correct, reinstall ChemDraw and see if that corrects the problem.

3. When reinstalling ChemDraw, make sure you right-click the installation file and select “Run as Administrator” to ensure all the registry settings are stored correctly.

4. If the issue continues, you may want to consider removing Biovia Draw to test if the association in MS Office goes back to normal.

5. If Biovia Draw is required for your work, then you can reinstall it again once the issue with ChemDraw is corrected.
