I upgraded from the Acrobat Standard X to the Pro, and this is what I did. First I deactivate the Standard and then uninstalled it. Next I installed the Pro, linked the serial numbers as prompted, and then tried to run the program. What I have is the Standard all over again only it says Pro. I have to have the preflight feature in my line of work. On this version, there is no Advance pull down window across the top or a document or forms tab. I am familiar with Pro 9, but X is not at all like the old Pro 9 I have used for years. What went wrong?
