Base module 'base' is not available

Installation and Licensing

When trying to open PowerFactory I get the following message:

"Base module 'base' is not available. Check number of concurrent PowerFactory users. Do you want to review your licence configuration?

Another possible message depending on the version:

"No base module licensed"


This error is related to the number of users connected to the licence. If the number of concurrent users is exceeded, PowerFactory won't be able to start.

The number of users connected to the licence can be verified using the link http://localhost:22350/license_monitoring.html
