Acrobat Pro not working after new hard drive installed
Hi, and thanks for helping. My hard drive failed this month and I had a new one installed - same computer, same serial number. I bought it a number of years back, and use it exclusively to combine multiple files into a pdf. No need on my end for any upgraded features.
I copied it over from my application folder (mac) but when I try to use it is says "configuration error: please uninstall and reinstall the software." Though I still have my activation key, I have no way to enter it, and I assume I can't download a much-older version of the software into which I could put my activation key.

Like I said, no need for a fancier version and no budget for a monthly subscription to a program I use six times a year to make a pdf. Anyone have an idea as to how I can get my program working again?
Thanks so very much!
