I have a customer that wants to upgrade her systems to windows 7 home premium for her business and I can't get her Embroidery Office software to recognize the CODE KEY that is installed in the parallel port. I have contacted Sierra Southtechnology and all they want to do is sell an upgrade to the program, which the customer does not want! The question I have is there a patch or program that will allow the software to see the code key? Any help would be most helpful Thanks
