To resolve the issue:
- Open the Registry Editor. Always back up the whole registry before making any modifications. Incorrect changes to the registry can cause serious system problems.

- Look for the "IsDisabledTrendProtect" registry key and change its value to "0".
- Close the Registry Editor.
- Click on the TrendProtect toolbar and select Enable TrendProtect.
The TrendProtect toolbar will now be enabled.
