Running software referenced by Bimmergeeks on my 2020 Dell laptop with Windows10 (i7 CPU) which provides access to the three programs I use on my BMWs: INPA, NCSExpert and ISTA. My cable initially came with software from a Romanian seller which I installed on a "retired" Windows XP desktop. I still use that occasionally.

The install on the laptop needs to be done according to the instructions but has been running flawlessly. I also run the software for my Tundra on my laptop and that was a lot more fiddly to get it to work. For the BMW definitely no need to get the 20 yr old laptop :-).
