I have Adobe Acrobat XI Pro installed on my PC, but I am having problems with my hard disk drive (some bad sectors). As a result I just bought a new HD but I do not know if I unistalled the current one and them re-installed in the new HD, or
if I need to follow some requirements. I use this as a tool in my jobs and I do not want to have to buy a new license one.
You won't be successful if you try to move it from one machine to another... it just doesn't work. You need to install using installation files. You do not have to buy anything again to get it on a new machine. You can download it thru the link below and use your serial number from the original to activate it.

You normally have an allowance to have two activated installations, so you do not neceesarily have to do anything more than install and activate if you only have the one original installation. But you can contact Adobe Support thru chat and ask them to reset your activations so that you will still have two available in case you ever have need for a second/backup installation.
For the link below click the Still Need Help? option in the blue area at the bottom and choose the chat option...
