Can I translate 32-bit ics format to any 16-bit format?

Dear all,

I am a completely newbie biologist trying to use ImageJ, so I apologise for
making so simple questions.

I acquired 3D photos with NIS-Elements (.nd2 extension). They were 16-bit.
I translated them to the ICS format (.ics and .ids extensions)
I deconvolved them with Huygens Essential and, if I well understood, as
energy was relocalized during deconvolution, it shifted to 32-bit.

Now I cannot quantify them back in NIS-Elements becatuse 32-bit images are
not supported.

CAN ImageJ TRANSLATE 32-bit ICS IMAGES TO 16-bit ONES?

When I try to open them at ImageJ, an "Exception" window appears declaring:

What can I do? I have got the feeling I am quite lost...

Thank you very much for your comprehension.
