Nothing is loaded when attempting to import a point cloud file in the FLS format (Faro) - the project is empty.
Try to unregister and register the iQOpen file (DLL) of the Faro engine in the Windows .NET assemblies folder:
C:\Windows\WinSxS\amd64_faro.ls_1d23f5635ba800ab_1.1.502.0_none_347e8ae1032f54af\iQOpen.dll
or (if exists):
C:\Windows\WinSxS\amd64_faro.ls_1d23f5635ba800ab_1.1.503.3_none_34818da5032c9ddb\iQOpen.dll
You can do it by running the following DOS commands (as the Administrator) in the above mentioned folder:
regsvr32 iQOpen.dll -u
and then:
regsvr32 iQOpen.dll
This should restore functionality of the Faro engine.
