I have an Ipaq PDA it has an older version of windows pocket pc version 3.0.11171 build 11178

I have tried the files from Adobe but have no joy? Also i can't see the PDA on my laptop (vista) could it be due to an older version PDA?

Any files i want on the PDA i just copy to the AD card. Would i be able to put the download file on an SD card and run from there on the PDA
