I had a similar problem for another data card. This got solved by following the procedure mentioned in the below link
BSNL EVDO Capitel Connect Driver Solution for Windows 8 | India Everything
Here, after installing the modem, go to the device manager and select the device and change the driver path. I found this method simpler. However, after following this method, sometimes I have had to kill and open the device a second time for the software to detect the device.
