That typically means that there is no valid license installed. (It could also mean LeanFT is not enabled, see instructions below). You should see a message saying, ''To install a license, run the Functional Testing License wizard from the Start Menu. When finished, exit and restart the LeanFT runtime engine.'' This should be on the path Start>All Programs>HP Software>HP LeanFT>Tools>Functional Testing License Wizard, unless it was installed to a different location.
After installing a license, you'll need to go to Start>All Programs>HP Software>HP LeanFT>LeanFT Runtime to activate the runtime engine. Next, in Visual Studio, click LeanFT then Enable LeanFT. The OIC should now be available.
