HP Ipaq 514 does not start with .Net Framework Problem

OS: windows mobile 6 standard
1. I copied NETCFSetupv35.msi (Microsoft.net Compact Framework 3.5) onto my storage card
2. I clicked on it
3. I got an error message: If it is on the storage card it has to be reachable
4. I rebooted my device
5. welcome screen appears immediately, but it freezes:
blue hp screen "iPaq 500 series voice messenger 2.05.00 0.76”
6. it happens with or without the storage card.
How can I solve the problem?
