Custom Step Type on TS 2017 compatible with TS 2016, error -17339

Hi,

I created a custom step type in TS 2017, and I checked the option in Version > Set Earliest TestStand Version that can Use this Type to 16.0.0.0.

Then when I tried to load the step type in TS 2016 I got this error: 

---------------------------
Sequence Editor
---------------------------
Unable to read object: object name not found.
The types file 'C:\Users\Public\Documents\National Instruments\TestStand 2016 (32-bit)\Components\TypePalettes\Test.ini' could not be loaded.

Error Code: -17339

I created a very simple Step Type and I got the same error.

Some ideas?

Thanks,

Freddy
