I am using Adobe Acrobat X Pro, 2010. I am using OSX 10.11.4. It is saying that this is an upgrade and the previous version is not installed. I was using Adobe Acrobat Pro for windows and lost it in a fire. I purchased a Macbook Pro and the Adobe Acrobat X Pro at that time. Customer service helped me install it. I have replaced the hard drive and need to reinstall it. David N.
