Cannot get Trust Bluetooth 3.0 USB Adapter to work

[whatever61]

Cannot get Trust Bluetooth 3.0 USB Adapter to work (it's a USB dongle).

Trying to install Bluetooth drivers (Bluetooth winsuite), provided by Trust, when the installation comes to an end, it rolls back the changes and tells me that The wizard was interrupted before Win7 Suite (64) could be completely installed.

I tried on another PC and it works. However, on my PC it doesn't.

Tried to plug in the device, then it just doesn't recognize it. Tried to install the drivers while the device is plugged and while its unplugged also.
Bluetooth service in the Services of Window is on.
Tried to disable firewall, windows defender, tried to run as administrator.
Tried to download another driver from Trust website.
I don't see any hotkey enabling/disabling BLUETOOTH.

My PC: Asus N73SV-V1G-TZ416V
Windows 7 Ultimate 64bit

I don't think its related, however, I manually replaced the wireless adapter, which came with the laptop, which apparently was a combination of WIFI + BLUETOOTH to another wifi adapter: Intel N-6300 633AN, which doesn't have BLUETOOTH built in (that's why I bought the bluetooth dongle).

Can you try to open regedit and go to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager

then on the right hand side delete the value PendingFileRenameOperations

run the installation and see if it helps.Also Disable User Access COntrol ( UAC )

Tried to delete the PendingFileRenameOperations value - didn't help.
UAC is always OFF on my PC

anymore ideas?
