OK, all is working with the midmark IQecg on my 64 bit Win 7 Pro machines. Indeed the 64 bit machines needed the 64 bit drivers, which were not included in the amazing charts install package. I called midmark. The drivers are on the midmark website, but not on the IQecg product page (like when you need a driver for a printer you goto the manufact website and pull up the product and there is a tab for drivers). The drivers are at midmark.com / drivers . I will email amazing charts that they may want to consider putting the drivers in the package, or at least have a note on the interface page telling people that they will need to get the drivers.
