Thanks so much Harold & Tess for your latest inputs on this. Fantastic that this issue seems to be resolved now and we can finally allow Windows updates without fear of corrupting Maximizer again. We're based in Canada and have been using this product since 1995 as well, and love it for it's simplicity and efficiency at doing what we need - just adding & printing notes for history, setting hotlist reminders and printing labels. Have never found the other plug-ins like campaigns, opportunities, customer service to be of much use. Upgrading to the cloud version seems ridiculously expensive for what we use it for. Wish us all good luck going forward and hope Maximizer keeps working for us for a few more years!
