Applies to: ScheduFlow Desktop, TimeFlow Desktop, and any products that require registration keys

If you are receiving the following message when trying to add the key to the license manager: "Invalid Registration Key" or "Key Already Exists" you are probably mistyping the registration key.

If  you have purchased our software from a retail store or a reseller:

1. Make sure not to confuse capital i's and lowercase L's.
2. Scan the back of the CD case that has the license key and attach it to your ticket or fax it to us at: 951.344.7304. 

Please make sure you provide a valid and legible email address in the ticket or fax so we can send you back the license key by email -- you can then just copy and paste it into your license manager.


If you purchased our software from our website:

1. Copy and paste the key into your license manager that would be the best option to avoid typing errors.
2. If you are typing the key in manually check to make sure not to confuse capital i's and lowercase L's.
3. If you are still receiving an error,  please submit a trouble ticket. One of our representatives will point out where the mistakes in your entry are.

Registration keys are generated automatically and do not have errors.
