Heres the trick to installing Sprint card 597 by sierra unto Windows 7.
Install smart view by inserting your card, you will get smartview and not the drivers installed but thats okay.
Now go to device manager and install the drivers manually, modem port, network adapter and the serial ports.
Right click and update driver software. now click on search manually and point to c:\program files\sprint\sprint smart view\sierra package\drivers-----then hit okay and it should install every driver flawless. You might get an error on the network port where it would say it wont start but it wont matter. click on your smart view and walla your connected!!
let me know if any problems are encountered!
Thanks
