Reader | 64-bit Font Pack and Spelling Dictionary for 2025 Version

@DanielJordan it's a mismatch issue when trying to install the Asian Language and Spelling Dictionaries for Adobe Acrobat Reader DC. The error message "Adobe Acrobat Reader 23.008.20421 or later must be installed before proceeding with this installation" clearly indicates that the installer you're using (AcroRdrALSDx64_2300820421_all_DC.msi) is looking for a specific minimum version of Adobe Acrobat Reader, which is 23.008.20421. However, you have version 2025.001.20577 installed. While 2025 is a newer release year than 22 or 23, Adobe's version numbering for Acrobat Reader can sometimes be a bit confusing. It seems the installer for the language pack is strictly checking for a build number from the "23.x.x" series, not just a newer year.

Try finding and downloading the language pack installer specifically designed for your 2025 version of Acrobat Reader DC, you should be able to bypass the version check error and successfully install the Asian Font and Spelling Dictionaries.
