If you are using CONTENTdm Project client 6.1.2.991 or earlier and you used the built-in OCR in the project client, you need to request a new license key for the OCR unit included in your CONTENTdm Annual Services Package. OCR codes in CONTENTdm Project Client 7.x are not compatible with OCR codes in versions 6.1.2.991 or earlier.
