As mention in another thread, the orbiter only appears to support a limited number of Windows CE versions. Here are my experiences with WM2005 and Pluto 0.32, incase it is an easy fix as it appears to _almost_ work.
Initially I browsed to my Pluto admin site using pocket IE and downloaded the Windows CE installer directly to my PDA.
The installation appeared to go fine, an added a pluto orbiter icon to my list of programs.
When I first started the orbiter and entered the address of the core, it asked if this was a new device or if there was an existing device id.
I selected a new device and answered the questions that followed (which user, room, screen size - I selected 320x200 obviously).
After that it gave me the progress bar where it showed the orbiter screens being generated.
Then windows asked me if I wanted to run a particular file, I beleive it was called something like datebinary.exe.
I said yes and the orbiter program closed soon after that and took me back to the list of programs on the device.
Shortly after that, the orbiter started up again and I saw a few lines in the log, ending in 'got the config, parsing configuration data'.
Then it just sat there until after about 30 seconds or so, windows gave me a message saying my storage memory is critically low.
The device then appears to lock up and requires a restart.
After a restart, I have the following memory usage:
Storage: 14.69MB free (out of 30.53MB)
Program: 73.19MB free (out of 88.33MB)
RAM Disk32: 29.96MB free (out of 31.42MB)
The orbiter program is installed on the RAM Disk32 partition.
I would assume that the orbiter wouldn't require more than 14MB of storage space?
My device is an XDAII, and according to the about screen, the OS version is 5.1.1700
