I've read the Inflight Installation Guide and the thread Running on Navman - booting without access to Explorer. My situation is a little different in that the PDN has been unlocked and I have access to the file structure. However when I double click on skydemon.exe I get the error message 'Cannot find Skydemon (or one of its components) ... all libraries are available'. Can't think it matters but, because I had problems getting ActiveSync recognising the Navman, I simply copied the extracted Skydemon files onto the SD using a card reader. Any suggestions?
