Hi Andrew,
Good question. I'm not sure if it has been tested on Windows 7.
Is that on 32-bit or 64-bit?
Has it created a bpbible.exe.log file? If so, what does it say?
Were you able to use it to add the books that are displayed on the screen in that screenshot, or were they already on your computer?
Have you used BPBible 0.4.7 (or an earlier version) on that computer?
Thanks,
Jon
