If by "install" you mean downloading the modules from the
Pocket eSword site to your Desktop PC and running the executable while you are "synched" to your Axim, then yes.
I don't know how similar the process is on the X5 (I have the X51v), but here is what I did:
1. Plug my Axim into its cradle
2. Get an ActiveSync connection
3. Browse to the Pocket eSword
4. Download the modules I wanted to my desktop PC
5. Run the executables (to install from your Desktop PC to your Axim)
6. Rinse and repeat step 5 for all downloaded
I installed Pocket eSword into the main program memory, and the modules onto my CF card. That is seeming to work out pretty well for me.
Good luck! (well, if you believe in luck anyway)...I should say "Good prividence!"
In Him,
Jeff.
