I am getting the 'Error 1' message when I try to open combined PDF files. I am also unable to combine PDF's and it says to uninstall and reinstall product which I have tried on many occasions.
Thank you Chancie

Chanice there is not a software offering titled Adobe Acrobat XI Downloader. We do have Acrobat XI Professional and Acrobat XI Standard available for Windows. Which one of these software titles are you using exactly?

Mnqps Gilad is correct you will need to utilize the Acrobat XI Professional trial or purchase the software. You can find more information at https://www.adobe.com/products/acrobat.html?promoid=JOLIR.
