Please have some patience and read it completely for the entire description ( I know it's too long for a post). I am using the Home 500 scheme of BSNL for the past 3 months using BSNL's provided C2110 modem. Firstly, I could begin using the Broadband connection 209 days (roughly 7 months) from the date of application. Secondly, inspite of being a fairly tech-savvy person (at least never before have I faced a problem in installing anything, not even formatting my PC and installing XP) I was unable to install the modem drivers from their provided CD. All that their Readme file provided is:

"
Welcome to use our product.

Driver version:V2.0

If you meet some problem, please read the user manual.
"

Everytime I tried installing it, I got the same message
"There is a problem installing the drivers for your modem"



Then all I could do was ask for modem installation from them (and had to pay Rs.250 grudgingly through my next bill exclusively for that) and that BSNL fellow used the same driver installer files from the same CD on the same PC in front of me in the same way I had tried fruitlessly so many times the previous week. After some time when my PC became slow I wanted to format it again (since I keep on experimenting with a lot of softwares and all). But since I didn't know how to install those modem drivers, I dual-booted on my other hard drive partition and tried it out but without any success. The same error message is flashed.
Can anyone guide me in which step did I get the thing wrong?

At first when I switched on my PC and the modem, I got this wizard-launching window "Found new Hardware".



And inspite of having tried out virtually all combinations here, I have always ended up with the following notification on my screen:
