I was trying to install the add-in of Refwork Citation Manager from Microsoft AppSource. The link is as below:
How ever, the add-ins was unable to be added. It was showed in the Word as below:
Add-in Information: Microsoft 365 has been configured to prevent individual acquisition and execution of Office Store Add-ins.
If at all possible, please let me know how to install the add-in.
Great thanks in advance.
