I set up Amiga OS 3.2 from Emu68 imager (without newicons). I found I could not mount ADFs.
I updated to 3.2.3, ensured DefIcons is running, but still, when I double click an ADF it just wants to execute it and fails. Icon looks like a hammer.
I suspected maybe DefIcons needed newicons to function properly, but I just don't know.
Could someone please help 
Thank you!
Sounds like you have overwritten the deficons with newer ones without the correct tooltypes defined.
Try copying back the original deficons from the AmigaOS3.2 CD. Then go from there.
