The modem was working fine with Windows XP, but now my OS is changed to Windows 7. iZAP is not working. How can we upgrade the modem so that it can work with Windows 7?
Unfortunately, the only drivers available seem to be for Windows XP and below. You can't update the modem because there isn't an online resource available for this purpose. You can try to install the drivers using Windows 7 Compatibility Mode, or alternatively you can use Windows XP Mode.
