Was just doing an a long overdue update of my PortableApps library, and the Launcher Updater is refusing to update Geany Portable. From the 404 message, it appears to be looking for the wrong filename/URL - there is no .paf.exe in the filename that the update is using, just .exe, whereas the sourceforge copy does end .paf.exe
You can see a screenshot of the error message here : https://www.dropbox.com/s/0x44sblnfp99z7e/Screenshot%202016-05-26%2011.2...
You're right, there was a typo in the updater database. It's been fixed. Sorry about that.
Sometimes, the impossible can become possible, if you're awesome!
No problem... thought you'd like an easy fix! Can confirm it's fixed, it just updated.
