How to Fix the Spellchecker in MS Word

Do you get these error messages when you click Spelling & Grammar or hit F7? It says no errors were found even though you can see them in front of you?

  • The spelling and grammar check is complete.
  • Proofing Tools are not installed for default language, try re-installing proofing tools.

Why is this happening?

There are different reasons:

  1. Proofing tools are not installed.
  2. The Speller EN-US add-in is disabled (ie turned off).

  4. The ‘wrong’ language is set as default.
  5. This subkey exists in the registry: HKEY_CURRENT_USER\Software\Microsoft\Shared Tools\ProofingTools\1.0\Override\en-US
