Did you install Acrobat from Acrobat Pro EFG installer? If yes, then you can change Acrobat language by following the steps below:
1. Launch Acrobat.
2. Open the Preferences panel from Edit->Preferences.
3. Go to International tab.
4. Change "Application Language" to "Choose at application startup"; click OK.
5. Close and re-launch Acrobat.
Now you will get an option to select the language when Acrobat launches. Choose English.
Hope this helps!
