Safely remove the older version of Acrobat to prevent version conflicts and ensure your PDFs automatically open in Acrobat XI.

Keeping multiple versions of Adobe Acrobat installed simultaneously is generally not recommended. It often leads to file association conflicts where the operating system gets confused and opens PDFs in the older application instead of the new one.

You can easily remove Acrobat 5 without affecting your saved documents, and then explicitly set Acrobat XI as your default reader.

Frequently Asked Questions

Will I lose my PDF files if I uninstall Acrobat 5?

No, your PDF files are saved independently of the software. Uninstalling Adobe Acrobat 5 will only remove the application itself, not the documents you have created or downloaded.

Why do my PDFs keep opening in the older Acrobat version?

When multiple versions of Acrobat are installed, your operating system's file associations can become confused, often defaulting to the older version. Uninstalling the older software and setting the newer version as the default app resolves this.

Can I reinstall Acrobat 5 later if I need it?

Yes, as long as you have the original installation media and license key, you can reinstall Acrobat 5. However, it is generally recommended to stick to newer versions for security and compatibility reasons.

How do I change the default PDF viewer on Mac?

Right-click a PDF file, hold the Option key, and select 'Always Open With'. Then choose your preferred PDF application, such as Acrobat XI or WPS Office, from the list to set it as the default.
