I purchase Adobe Acrobat 9 Pro a couple years ago. It is installed on my HDD drive but I recently added an SSD drive and want to get it installed on there. I don't mind taking it off my HDD drive, I just want it to be on my SSD drive, but when I try install it using my old serial number it says that it is now invalid. Is this because I can't install it twice? What do I need to do to get it installed on my new drive? This is on the same computer.
Thanks,
Jason
