Here's the URL to what I downloaded (based on a pointer in these forums):
http://tbp.freespacemods.net/TBP_v3.4b.exeThe fs_open_3_6_9.exe, fs_open_3_6_9_INF.exe, and their two debug equivalents all have the B5 logo. In the same directory are fred2_open_3_6_9.exe, fred2_open_3_6_9_INF.exe, and the two debug pairs, all of which have the Freespace icon.
Here's the directory listing:
