The LanguageTool Word add-in icon is greyed out

If the LanguageTool Word add-in icon is greyed out and unavailable, it may be because your document is using an older or incompatible format such as .doc or .odt.

How to fix this

To use the LanguageTool Word add-in, you need to convert your document to the .docx format:

1. Open your document in Microsoft Word.

2. Click File in the top menu.

3. Select Convert.

4. Save the document as a .docx file.

After converting, the LanguageTool add-in should become active and ready to use.
