Some time before 2010, my father worked for a company which bought CS5 for all its employees. Someone installed it on my father's personal computer without registering it, and when my father began to work for another company which gave him a laptop, he gave the computer to me. I want to open backsaved CS6 IDML files with it, but am worried that the plugin updates will require Adobe ID with registration, which I do not have. Does anyone have any information or recommendations about this?
