Customer Service: I get this message when entering a new activation code, "Activation succeeded but no activation licenses were found"

I get this message when entering a new activation code, "Activation succeeded but no activation licenses were found"

1. You will always receive an Activation ID/Host owner mismatch error when the computer that you want to activate was previously registered under an activation code for a different account. The only way to fix this is by providing the Host ID to our support team so we can take care of the problem. The Host ID can be found on the Activation screen. 

If the activation code is part of a multi-user license, then it's also possible that the new activation code you received is under a new account name on our activation server. We can search the devices activated under the original account to fix the problem on all of them.

2. If this error message also contains "(The host ID is marked as returned)”, this means the PC Host ID has been marked as unusable for ChemDraw. Please Contact Technical Support with the Host ID to have it reinstated.

3. Please check the start date of your license in the Download Center. You will receive this error if you are attempting to activate the license before the start date. To fix this issue, please use your license with an appropriate start date or contact Technical Support for more information on your license.

4. Please check the version of ChemDraw that you have installed. If you have a perpetual license, you will receive this error if there is a mismatch in the license purchased and the software installed (e.g. You are attempting to activate a ChemDraw v20 perpetual license but have ChemDraw v22 installed). If there is a mismatch, please either install the correct version of ChemDraw for the license or use the correct activation code for the installed software.

Note: Perpetual licenses need new activation codes for every new version. Subscription licenses do not require separate activation codes for higher versions.
