Nationalinstruments.UI.WindowsForms.Led does not show up.

[loti]

I have a problem.
Nationalinstruments.UI.WindowsForms.Led does not show up.
Development Environment: Measurement Studio 2015 with Visual Studio 2013

There is no problem on the PC Where Measurement Studio is installed.
but Nationalinstruments.UI.WindowsForms.Led does not show up on the PC Where Measurement Studio is not installed.

I have included the necessary .dll in the install package. (NationalInstruments.UI.dll, NationalInstruments.UI.Styles3D.dll, NationalInstruments.UI.WindowsForms.dll)
And other Measurement Studio's controls(NumericEdit, WaveformGraph, etc.) show up.(no problem)

How can I resolve this problem?

I solved the problem myself.

The value of the property should be 'Round' instead of 'Round3D'.  

But, I don't know why.
