Try getting a driver only package for your modem. Thier available online just google the model number of your dongle and drivers. I had a similar problem and just didn't bother with the vmclite software.
double check that the dongle is picked up at all in system it may come up as an unknown device or such like; open the device and choose to update driver; point the location to where you downloaded the .inf files (I used the winxp driver inf files) too and it should resolve your issue.
if the device still is not picked up try it in some other usb ports and repeat the above.
