Uninstall Acrobat 2017 and Install Acrobat DC via Creative Cloud

Since Acrobat 2017 and Acrobat DC cannot co-exist on the same system, you must completely remove the older version before installing the new one.

Adobe does not support installing multiple versions of Acrobat Pro or Standard on a single computer. The presence of Acrobat 2017 creates licensing and background process conflicts that cause the Creative Cloud installer to stall.

1
Uninstall Acrobat 2017

Navigate to your computer's 'Programs and Features' (Windows) or 'Applications' folder (Mac). Locate 'Adobe Acrobat 2017', select it, and follow the on-screen prompts to uninstall the software.

2
Run the Acrobat Cleaner Tool (If needed)

If the uninstallation stalls or fails, download the Adobe Acrobat Cleaner Tool from the official Adobe website. Run the tool to wipe any lingering registry keys and installation files.

3
Restart Your Computer

Reboot your machine to ensure all Adobe background services, such as the Adobe Genuine Software Integrity Service, are fully terminated.

4
Install Acrobat DC

Open the Adobe Creative Cloud desktop application, navigate to the 'All Apps' section, locate 'Acrobat DC', and click 'Install'.

Frequently Asked Questions

Can I keep Acrobat 2017 and Acrobat DC installed on the same computer?

No, you cannot have two different versions of Adobe Acrobat Pro or Standard installed simultaneously. Doing so causes licensing conflicts and causes the software to stall or crash.

Will uninstalling Acrobat 2017 delete my saved PDF files?

No. Uninstalling the Adobe application only removes the software itself. Your personal PDF files stored on your hard drive or in the cloud will remain intact and completely safe.

Why does my Acrobat DC installation stall in Creative Cloud?

Creative Cloud stalls because it detects background services, registry keys, or licensing files from an existing older installation (like Acrobat 2017). Using the Adobe Acrobat Cleaner Tool and restarting your computer usually resolves this.
