Today I tried using my bluetooth and realized it was missing.
I went to my "Devices Manager" and it wasn't showing any Bluetooth devices.
However, following the instrucions in this question, I enabled "Show hidden icons" and it was listed. As there wasn't any "Bluetooth Generic Adapter", I followed the accepted answer on that same question, and uninstalled all Bluetooth drivers of my "Device Manager".
When I restarted it didn't try to reinstall any drivers, so I went myself to Acer site and got Bluetooth drivers.
I installed it, restarted, but the problem remains and it's worse, as no bluetooth devices are shown in Device Manager.
If I click again in the driver installer, it shows the options "Repair", "Alter" and "Delete" as if it was already installed.
I also installed "Driver Talent" and it shows no problems with my "Bluetooth USB Device", but of course there is a problem, since my Bluetooth disappeared together with its devices.
It is a new computer, just a couple of months. However I bought it in another country, so I can't use it's warranty....
