Summary:
Can I run CitectSCADA Pocket in demo mode without a key?

Or...

CitectSCADA Pocket displays this error after running for a while:

System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.InvalidOperationException: No hardware lock present... 


Solution:
If no Pocket license is found the web service will run for 30 minutes. During this time it will allow clients to connect and view/edit data from Citect. After demo mode expires, the server returns "No hardware lock present" errors. Citect may also be running in demo mode (see KB Article Q2255).

When the Pocket Server's demo mode has ended, it may be restarted. Go to the Windows Control Panel | Administrative Tools | Services. Right-click on World Wide Web Publishing Service and choose Restart.
