If you still want to try the Dropbox route here are some questions/suggestions.
Always difficult to diagnose for someone else when it is working here. Some suggestions a bit silly, clutching at straws.
I haven't seen any other comments on the web of the Dropbox/Bluefire reader combination failing to work.
Just double checking.
- You did use the right hand of three top right icons in Dropbox, with the arrow pointing down into the box? (Goodness knows what that is meant to mean!)
Sounds as if you must have done, otherwise it would't have come up the the 'no installed apps' message. - Have you authorised the Bluefire reader to your AdobeID?
I would have thought that if you hadn't, it would be the Bluefire reader that said it couldn't open the .epub,
rather than Dropbox not knowing about the Bluefire reader. But ...??? - Have you run the Bluefire reader on the iPad.
Maybe on first run it does something to tell other apps around that it exists? - I have the following versions installed on the iPad. Some difference here could be what is making mine work and yours not?
- Dropbox Version 2.0
- Bluefire Reader, Version 1.9
- ios version 6.0.1 (10A523)
- iPad 2 (apparantly model MV775B)
I just did another experiment and found that transferring the .acsm file via Dropbox works as well (for me).
When the .acsm file is displayed in Dropbox on the iPad it displays the xml content of the file, but still has the dropdown for 'Open in Bluefire Reader'.
Opening this caused Bluefire to re-dowload the .epub file direct to the iPad.

Another suuggestion I have seen ( http://www.pldminfo.org/search/digitaldownloads/iPadBluefire.pdf ) to avoid the need for iTunes
is to mail the file to yourself. I've just tested that with both .acsm and .epub files and it works for me.
It probably uses the same 'cross-application' mechanism that Dropbox uses to open files,
but maybe for some reason it will work for you where Dropbox failed.
I checked through all of the points that you mentioned should be inplace and found that I failed to authorise Bluefire to my Adobe even though I was shure I did. Low and behold the file opened.
Thank you so much for your patience and assistance.
