OrcaFlex licence monitor

The Orcina Licence Monitor is a service that allows you to configure your OrcaFlex installations to report their real time usage of both local and network licences.

The Orcina Licence Monitor (OLM) is a service that monitors the current number of OrcaFlex licences claimed on a network in real time. Other programs that use the OrcaFlex programming interface (OrcFxAPI) such as Distributed OrcaFlex and the OrcaFlex spreadsheet are also monitored. You can obtain information on each licence claim that includes:

  • Network information: the computer name, network address and the user name.
  • Licence information: the dongle name, the dongle type (network or local) and the time the licence was claimed.
  • Program information: which modules are being used, the version, and the location of the program which has claimed the licence (usually this is OrcaFlex.exe but it can be Excel.exe for the OrcaFlex spreadsheet for example).

OLM requires OrcaFlex version 8.7a or later.

The latest version of OLM is 1.4d which includes the following changes over the previous version (1.4c):

  • Updated the Orcina logo to the new version.
  • Applied maintenance updates from the code base shared with other Orcina programs.

Downloading and Installing OLM

The latest version of OLM (1.4d) can be installed by following these steps:

1. Download OLM Manual.pdf which contains documentation for OLM including an installation guide.

2. Download the following zip file:

Unzip the contents, and run the extracted file OrcinaLicenceMonitor.msi.

Configuring OLM

The Orcina Licence Monitor relies on OrcaFlex reporting to the OLM Server when it is using a licence. For this to happen, OrcaFlex needs to know where the OLM Server is and looks for this information in the Windows registry. When installing the OLM Viewer component on a user’s computer you will be prompted for the OLM Server address and the installer will set the registry with this value. If the OLM Viewer is not being installed on the computer running OrcaFlex then the registry needs to be set manually. The registry key and setting are:


The data is the IP Address or Hostname of the OLMServer. OrcaFlex displays the OLM server address it finds in the ‘About’ information under the main ‘Help’ menu.

The dongle supplier (Sentinel) provide their own licence monitor, AKS monitor, that reports information on network licence usage only. However, this monitor obtains the information directly from the licence manager and so is a useful tool in locating OrcaFlex installations that are not reporting their usage to the OLM Server correctly. The AKS monitor can be downloaded from our Licence Support page.
