I've been using InDesign CS-4 for 32-bit on my former laptop, but have just purchased a 64-bit laptop. I've trying to reinstall CS-4. When I start the process, I enter the CS-4 serial number;then it asks for the serial number of our previous product because it doesn't find one on the new laptop. We have the serial number for PageMaker 6.5 Plus, but the screen won't accept it. The last time this happened they told me I needed to get a special code from a service technician, but of course, that was a couple of years ago and I they don't accept those kinds of questions for an old product Anybody know how I can work around this?
