1. Please verify that your customer has a product ID that begins with "IFS".
2. You can then give them the registration ID # 0300-3054-0940 and have them re-run their installation.
**Please do not use this temporary Reg ID after April 15.**
After that time, the customer can simply re-register with their
original Product ID and they will receive a new Registration ID.
