When starting the service I get an error-message saying: “Installing service….failed. Error whilst installing service.

You have installed the license server for MODDE 9.1/SIMCA 12 on the same server as SIMCA 13. In this case you need to install and start the license server for MODDE 9.1/SIMCA 12 before you start the license server for SIMCA 13. If you have installed the SIMCA 13 license server before the one for MODDE 9.1/SIMCA 12, the license server for SIMCA 13 needs to be uninstalled. After SIMCA 13 is uninstalled, install the license server for MODDE 9,1/SIMCA 12 and start the license server. Then install the license server for SIMCA 13.
