Can't upgrade from Adobe Acrobat Pro X installed with CS5.5 to Adobe Acrobat 2015
I wanted to upgrade Adobe Acrobat Pro X, so I clicked on the "upgrade now" link on the welcome page. It took me to adobe.com, where I purchased the upgrade to Adobe Acrobat 2015.
When I tried to install it, the installer prompted me for the previous serial number and product. Adobe CS 6 for mac was listed in the product dropdown to enter a serial number but not Adobe CS 5.5. So this upgraded version won't install.
Why not? The version of Adobe Acrobat Pro X that came with CS5.5 is the same as the version that came with CS6. It makes no sense that I can upgrade from the latter but not the former.
