for several months the auto update kept failing on DC program, and i tried to delete it and reinstall it but was not successful. Most of the files were removed but not all and now it won't reinstall at all no matter what way i try to do it. I have checked my firewall settings, enabled java and EVERY other fix that are listed on the help pages and NOTHING works.
As i was able to understand the issue, there is an issue updating as well as in reinstalling Acrobat DC on your computer, is that correct?
Assuming you have Windows OS installed on the computer, try running Cleaner tool which you can download from here: Download Adobe Reader and Acrobat Cleaner Tool - Adobe Labs
Reboot the machine.
Download and install Acrobat DC from here(subscription): Download and install Acrobat DC subscription
For perpetual license: Download Pro or Standard versions of Acrobat DC, XI, or X
Once installed, try updating Acrobat and see if that works. You may also visit the following link to install update manually:
Keep us posted with the results.
