How to get my cd copy of Adobe Acrobat Pro onto my Surface Pro

Hi,  I had a HP laptop and bought a CD of Adobe Acrobat Pro and loaded it onto the laptop.  That laptop died so I bought a Surface Pro but cannot find anywhere help to download Adobe Acrobat Pro onto my surface pro and use the original "key" to activate it.  I can only find to pay for a cloud app.  Can anyone help?
