Product & Version:

Adobe Acrobat Pro 2024 - Classic Release

Version 2024.001.30383 (64-bit)

Environment:

Windows 11 (64-bit)

Summary
Acrobat Pro 2024 exposes UI options for installing additional spelling dictionaries, but the installation process is non-functional. The application instructs the user to "install manually", yet no manual installer exists for Acrobat Pro. The only available dictionary pack (2023) is restricted to Acrobat Reader and cannot be installed in Acrobat Pro, leaving the feature unusable for non-English languages.

Steps to Reproduce
1. Launch Adobe Acrobat Pro 2024.

2. Open Edit / Preferences / Spelling.

3. Click Add Dictionary.

4. Attempt to add or install a new dictionary (e.g., Spanish, French, Portuguese).

Expected Result
Acrobat Pro should:

• Provide a valid dictionary installer compatible with Acrobat Pro 2024, or
• Allow installation of additional language dictionaries directly through the UI, or
• Disable or remove the dictionary-installation UI if the feature is not supported.

Actual Result
- The Add Dictionary dialog opens, but no dictionaries can be selected or installed.

- Acrobat displays a message instructing the user to "install manually."

- No manual installer is provided.

- The only available dictionary pack (2023) requires Acrobat Reader and cannot be installed in Acrobat Pro.

- As a result, full spelling dictionaries for non-English languages cannot be added.

Additional Observation
The application successfully accepts the UK English dictionary when US English is already installed. This confirms that the dictionary system is functional for English variants. The failure appears to affect only non-English dictionaries, which consistently trigger the "install manually" message and cannot be installed.

This suggests the issue is not caused by installation corruption or OS configuration, but by missing or incompatible dictionary installers for non-English languages in Acrobat Pro 2024.

Impact
The dictionary-installation feature is completely non-functional for non-English languages in Acrobat Pro 2024.

Users can add custom words, but cannot install full language dictionaries, making spell-checking unavailable for Spanish, French, Portuguese, and other languages.

Severity
Medium-High

The UI suggests that dictionary installation is supported, but the required installer is missing or incompatible. This results in a broken workflow and user confusion.

Notes
- OCR language support works correctly (Spanish, French, Portuguese, English).

- The issue appears to be caused by Adobe discontinuing the dictionary installer for Acrobat Pro while leaving the UI intact.

- Multiple users have reported identical behavior.
