CSR Bluetooth chip

Hello, I bought a4tech bluetooth keyboard & mouse like this one https://www.shopon.pk/image/cache/catalog/products_2018/44-21-1000x1000.jpg long time ago and I'm trying to connect then to my laptop (Lenovo thinkpad win7). The laptop already have bluetooth but it isn't detecting the mouse and keyboard so I'm trying to use the bluetooth dongle that came with them but the problem is that I lost the mini CD that came with them so I'm trying to download the dongle drive by Internet. When I insert it, it shows a yellow mark (CSR Bluetooth chip) in the device manager under bluetooth radios tab.. I searched for that drive but I can't find it but only in that website http://primebetta.ru/1515090971s/ya...ze=no&year=2018&key=Csr+Bluetooth+Chip+Driver which is in russian and I don't know if it's a safe website or a scam because it demands me to register before downloading and when I tried to register it's telling me to send an SMS to some number..
So if anyone has that chip drive from another source I'd be grateful.

Thanks

I found the drive and installed it and the yellow mark is gone and CSR Bluetooth chip driver in the device manager is working properly, but it's not showing a bluetooth icon near the clock (

There are currently two bluetooth drivers on the laptop (the original one of the laptop and the CSR chip) and I have to disable one of them to make the other work.. The original bluetooth of the laptop is working with a bluetooth icon near the clock but as I said in the post it doesn't detect the mouse and keyboard when I try to add devices, and the CSR driver isn't showing a bluetooth icon so I can add devices (

I checked the batteries and all on keyboard & mouse and they're fine but I just can't connect them to the laptop.. Please help what should I do?
