Help for Windows Mobile Phone Application Update

hi i wrote a script to copy a CAB file via FTP from the distant server to the Mobile. This is all working fine and the size matches. Now my problem is when i am开发者_高级运维 trying to install the file on the Mobile, i receive the message "the install was unsuccessful" and when i copy directly from the server to the Mobile this is working Can you help me with this :-(

Regards

You say the file size is the same, but what about contents? Are the files identical? How are you transferring the CAB to the device manually? Over ActiveSync/WMDC? BE aware that ActiveSync may modify a file during transfer - especially if the CAB is signed and the device doesn't require signed CABs.

See this SO question for some background/similar behavior.
