Hunspell Spell Checker is Unusable on Your Platform Error

Problem

When trying to use the Check Spelling option, I receive the error Hunspell spell checker is unusable on your platform. It has crashed the application in a previous session.

Cause

There are instances where Oxygen XML Author Eclipse plugin determines that an internal component (such as the spell checker) has crashed the application and disables that component from running in the future (to prevent a possible future crash).

Solution

To re-enable the spell checker component, follow these steps:
  1. Close Oxygen XML Author Eclipse plugin.
  2. Open the %APPDATA%\com.oxygenxml folder and look for a file called something like HunspellCrashGuard*.txt. Delete that file.
  3. Restart Oxygen XML Author Eclipse plugin.
