It is not a matter of piracy but of convenience. RE: I want upgrade to Mathcad 11 from Mathcad 2000 IRstuff (Aerospace) 27 Oct 03 13:13Īt the time i started this thread I was seriously considering buying the upgrade but after learning of the activation feature I will not upgrade. You will find the article at the link below, including the mention of the fact that Tom Allanson, senior vice president of Intuit's consumer tax group, wrote an open letter of appology to TurboTax customers on Thursday. Perhaps you could profit and learn from other's mistakes and in so doing, re-examine the Mathsoft policy that places this abhorent technology in your products thus preventing me and other Mathsoft users from using their products both at home and at their offices.

This same technology is employed in your current Mathcad product. The worst sin was.that it affected their 'bottom line' sales numbers which suffered a major decline from preceding years. They were annoyed to the point of returning the product for full refund, vowing never to use the product again, and, filing a Class- Action lawsuit. The folks at Intuit were slow to learn that their users were extremely annoyed at the 'Product Activation' technology imbedded in their TurboTax program last year. It cost them a significant loss of revenue as people were not buying it and many of those that did, returned it, with complaint, for a $$$ refund They have removed from this year's product, and wrote a letter appology to their customers.Ĭonsumer revolt that impacts the 'bottom line' is still the most effective way to get the message across. sent to Mathsoft's Allen Radzow, Senior Vice President of Products and Services, re: the subject of Product Activation, relating the bad experience that INTUIT had with its inclusion in their TurboTax product last year.
