Hi Andrej
The QPAC's (Components) are not deployed by default.
The 7 Core QPAC's are included with the LiveCycle Workflow Server install and are in the QPACS directory.
To deploy any QPAC, follow the instructions on page 74 in the Creating Workflows.pdf guide which is in your documentation directory for both the Server and Designer.
The SDK is not installed. If you simply want to use the SDK QPAC's, then follow the same instructions as above.
