nscontactsbackup not executing

[jdoherty76]

I installed a freeware program called nscontacts backup to enable me to back up my contacts etc.. but when I execute this program I always get the following message:

nscontactsbackup.exe requires a newer version of microsoft.net compact framework than the version installed on this device

Can anyone help shed any light on what exactly this error is and how to circumvent it?

Thanks jd76..
