zte usb data card mg880

[Guest]

I purchased this zte mg880 data card for wireless net connection but after
installing the software it asks for device to be plugged in when i do so it
starts searching for driver and finally says no driver for this device.

I am using lenovo laptop with vista as preinstalled.. the card's description
says it works on vista but its not getting installed on my vista.

I have purchased an acer aspire 4710z
i have loaded it with vista
and have got a reliance zte mg880
but as soon as the setup program for this usb starts running., i get a
windows message box saying " installer.exe stopped working"

What must be the problem.?
