While trying to activate the product using my site subscription account, I see the error "Activation ID copies exceeds available copies" How do I address this problem?

We believe you tried to activate the product using an individual perpetual (subscription) activation code instead of the site subscription activation code.

Please login to your Flexnet account and click List Entitlements present under Activation & Entitlements.
Use any of the ChemOffice + Cloud/ChemDraw Professional/ChemDraw Prime site subscription activation codes.
