What Causes the Actian Zen/Pervasive 161 Error?
This error typically occurs in Windward System Five when:
- Your temporary Actian Zen/Pervasive license has expired.

Windward System Five Troubleshooting Steps
Step 1: Install Your Permanent License Key
- Locate the Actian Zen/Pervasive Key Code included with your Windward System Five software package.
