I've tried it with attracman, reflect, cools, and basic. I've also wiped out the folder entirely and re-extracted the zip file, so I have a clean install. The version number on the copyright in the menu does say 1.5.3, so I've got the right version. I've tested on an Intel integrated video and nVidia GTX 960.
EDIT: Oh snap yes as suggested in the github ticket, the 32 bit works perfectly. I have no problem using this, thanks!
