Install on WM6 Standard edition

Windows Mobile Smartphone

Am trying to install on my Dopod C730 WM6 Standard edition and it fails with this message:
"Cannot copy the file, Make sure the mobile device is connected, that the mobile device has space available and is not protected, and that all setup programs on this device have been completed"

Is there any way to fix this problem?
