We are testing the newest SAP Connector 5.90 IR 64bit and are not able to open the Extractor window/wizard of the SAPEXTRConnector. All other connectors seems to work fine.
We have installed the necessary transports (E66K900049, E66K900036) and started the SAP service with port 6880. The connection string could be created but clicking on the "Extractor" button freezes the window.
