How is the Licensed Version Delivered?

No new program files are needed if you already have the trial version! After receipt of your license fee, you will receive a User Name, Affiliation, and Serial Number via e-mail or fax. In combination, these will unlock the evaluation version and remove the 30-day time restriction. Therefore you must supply an e-mail address (preferred) or a FAX number so that you can receive your serial number.

The only functional difference between the registered and evaluation versions of the program, other than removal of the 30-day time restriction, is that for registered users the 'splash' screen sequence that is shown when the program starts may be replaced with a quick display of the program version and the registration information.

Please note that the program files are available only by downloading via the Internet. Diskettes cannot be supplied for both logistical and tax reasons.

Pre-paid Orders

Pre-payments by check or money order should be made out to 'John Philo, software consultant' and mailed to 3329 Heatherglow Ct., Thousand Oaks, CA 91360, U.S.A. Please print out and include the order form.

Paying by Credit Card or PayPal

Arrangements have been made with a major shareware software supplier, NorthStar Solutions, to accept orders paid by credit card (Visa, Mastercard, Discover, American Express) or PayPal. This arrangement is strictly for your convenience (e.g. easy currency exchange for those of you outside the U.S.); payment by purchase order is preferable. 

NorthStar will process orders at either the full or the academic discount price, as well as upgrade orders at either price. These are each treated as a separate product on the order entry web page. 

Credit card or PayPal orders may be placed on-line (e-commerce) at the NorthStar secure web site. They do not accept orders by phone, but orders can be faxed to 1-785-539-3743 if you give them the NorthStar product number (above), the credit card information, and the filled-out order form.

NorthStar Solutions does not accept purchase orders and cannot provide price quotations or answer questions about the programs. Please do not contact them about those things---they cannot help you, and they charge John Philo a fee for each such call or e-mail! 

You will also need to give NorthStar the user name and institution, and an e-mail address and/or fax number for delivery of your serial number to unlock the program. Note that what is needed is the e-mail or fax for the person receiving the license, not those of the purchasing agent! If the name on the credit card is not the end user, you should add the end user's name and e-mail in the comment section (or better still, also fill out John Philo's order form and fax that to 1-805-492-6413).

NorthStar notifies John Philo about your order by e-mail, so normally you will receive your serial number within 24-48 hours.

The NorthStar Solutions web site address is http://www.nstarsolutions.com The specific order page for these programs is http://www.nstarsolutions.com/store/home.php?provider=JohnPhilo or you can find the programs under NorthStar's 'Miscellaneous' category.

Purchase Orders

Institutional or company purchase orders can be accepted directly by John Philo, as long as payment can be made by check (not wire transfer) in U.S. funds, and provided that payment will be made within 30 days. 

Please also print out and include the order form with your order. 

Please note that NorthStar Solutions will not accept purchase orders; they must be placed directly with John Philo.

Also please note that academic discounts are granted solely at the discretion of John Philo. This privilege will be revoked for institutions that fail to pay promptly.

Using a purchase order generally will not significantly delay receiving your license. The license is issued as soon as an order is received (without waiting for payment). Also, if your trial period is expired you may wish to contact John Philo and ask for an extension while your purchasing bureaucracy generates an order.
