Hi and welcome :)

I am unfamiliar with Carrera Digital and Race Link.
Is the issue the fact your PC needs to have bluetooth, or something else ?
If the former you can buy a USB  "dongle" for Bluetooth, but I suspect that should not be required with Race Link.

I don't wish to sound condescending, but in order to start from the top have you followed the race link instructions to the letter ?

It appears Race link should work with these programs as well as the Carrera one:

PC Lap Counter (PCLC) Pc Lap Counter - Slot racing software - Lap Timer - Lap Counter - timing software

XLAP XLap download | SourceForge.net

Try the free trial of paid programs first to ensure they are suitable for your needs.
Hope this is of some help.
