Hello Charles,

Thank you for reaching out! It seems like you're experiencing an issue with the Antidote plugin after updating to version 5.0.3.0. Let me guide you through some steps to troubleshoot and resolve this:

**Step 1: Verify Plugin Compatibility**

- Ensure that the version of the Antidote plugin (5.0.3.0) is compatible with Trados Studio 2026. Sometimes, plugin updates may not align perfectly with the latest Trados Studio version. Check the plugin's release notes or documentation for compatibility details.

**Step 2: Reinstall the Plugin**

- Uninstall the Antidote plugin from Trados Studio.

- Download and reinstall the latest version of the plugin from the RWS AppStore.

- Restart Trados Studio after reinstalling the plugin to ensure proper integration.

**Step 3: Check Antidote Integration Settings**

- Open Antidote 11 and verify that it is set up to integrate with Trados Studio. There may be an option in Antidote's settings to enable or configure integration with external applications like Trados Studio.

**Step 4: Test with a Different Project**

- Create a new test project in Trados

I reinstalled the plug-in, but still get the same error message: Registry key not found. Make sure you install the 'Antidote' app before trying to use the plug-in

Everything worked well before the update.

I have Trados Studio 2026 and Antidote 9.

I tried those solutions. It still doesn't work

I tried all of this as well, with no success. Is there any way to contact the developer?

Does not start at all. keep me in the loop.
