Ever since the project maintainer John_IV got a 64-bit computer and operating system, and also considered the march of time and progress, he decided to stop compiling and releasing 32-bit builds of MAMEUI and switched to only providing 64-bit builds of MAMEUI. 32-bit builds are no longer offered at MAMEUI.info because he doesn't feel like making and supporting them.
So what happens lately is, every time the "official" 64-bit build and sourcecode is released, some kind soul other than John_IV (usually redk9258), usually on the MAMEWorld forums, compiles and uploads a 32-bit version to MAMEWorld forums.
For MAMEUI 0.159, that happened here:
Or more specifically, here:
Which is to say - the release of MAMEUI 64-bit (and its "unofficial" 32-bit builds) is usually announced on the MAMEWorld News Submission subforum - and NOT the dedicated MAMEUI & IV/Play subforum.
Usually AntoPISA later comes along and mirrors these builds on his MAMEUI page, which has already been pointed out to you.
Hope this helps.
