If you are using the correct drivers, make sure the failed install is fully uninstalled -- which may involve picking through the Registry.
But I wouldn't go on banging your head against a brick wall -- if the unit is newly purchased take it back and swap for a different model.
If older, you may have to buy a new one.
This TP Link TL-WN350GD is correctly previously worked in another computer with the same driver
Thanks for your advice, will look for a new Wireless card (from another manufacturer), I might have better luck
