My PC is a Dell Precision 7710 running Windows 7 Professional 64 bit OS. 32 GB RAM, with a 1TB SSD system drive.
I have trouble using Bluetooth on my Sennheiser Momentum Wireless M2 AEBT headphones.
In the device manager under sound video and Game controllers,
Bluetooth Audio properties, Device Status shows :
"Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"
If I try Update Driver software from the device manager(from on-line), all I get is a message saying that the driver is up to date.
I am unable to use Bluetooth with the headphones, the manufacturer's manual makes no mention of having to download drivers and there is no disk supplied with the headphones.
I would like to know:-
a) Do I need Sennheiser Bluetooth drivers, the current Bluetooth audio drivers are Motorola Solutions Inc. File version 17.1.1411.0498 (c) 2014
a) if I uninstall the Bluetooth audio drivers, are there Sennheiser drivers for windows 7 which would allow me to use the headphones via Bluetooth with Windows 7 ?
b) If the Windows driver files are deleted will the PC still start up ?
The current Bluetooth Audio drivers are:
