The archive with the program you have is called papb-win-32.zip, but after unpacking it and trying to launch the application, I receive a message about an incompatible operating system (I have Windows 7 x32), the archive most likely contains an application for Windows x64
You are correct, it looks like I chose the wrong build option. I had already meant to fix a few bugs in this eventually. I'll upload an actual 32 bit version in a few days when I have a new version.
