Trouble opening Andor SIF files in Fiji

I am trying to open a .sif file from Andor camera in Fiji and failing
-simply dragging opens the Bioformats Import, the TXYZ info is read correctly, but the signal is strange, as if the format of the numbers was wrong?
-I also tried to install the " ImageJ SIF Viewer" provided by Andor, but I’m confused. They provide instructions for Imagej, there are plugins files that should go to \plugins and two directories \win32 and \x64 containing dlls - where do I put these?
