Installer says My PCC is Expired? Your PCC was sent in an email to the contact on file when your subscription was initiated. If you have an annual subscription, that PCC can be used for the full year. But if you chose a monthly subscription, that PCC is only valid for a month. At that time, the system automatically updates your PCC internally. But if you have saved the delivery email with the initial PCC, and if you are trying to use it to install or re-install after that first month, you will receive some messages to the effect that the PCC you are using has expired. Don’t worry. At that time, you can contact us or use the automated system: to request your current PCC. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.enercalc.com/sel-faq/setup-and-licensing/installation-activation-lice/troubleshooting/my-pcc-is-expired.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
