Lite version and APG

Hi,
I had use Lite edition to generate the HDR. Look nice.
The problem is:
when load in Auto Pano Giga, to generate a panorama, it don't recognise the EXIF. None.
Say: No EXIF.
Load in PTGUI, same HDR files, make a very good panorama.
Irfanview display the Exif, but only APG, none.
What happens?
Tks,
