BMDA v2.0.0 + bmp does not start due to registry problem #2174

Description

@positron96

Hello!

I recently decided to update to official stable bmda v2.0.0, on Windows 10 x64. Before that I used a custom-built version from 3576cdf (which I used for a year or two), and it worked with the same hardware and on the same system.

Unfortunately, I can't get it to work with a physical black-magic probe (on a stlink). It crashes upon starting with this error, related to USB devices registry entry:

D:\Cloud\Programming\BlackMagicProbe>blackmagic-bmda.exe                                                      
Error opening registry key SYSTEM\CurrentControlSet\Enum\USB\VID_1D50&PID_6018&MI_02\&0002\Device Parameters, got error 00000002: The system cannot find the file specified.

Unexpected problems finding the device!                                                                                                                          

Indeed I don't have the aforementioned registry keys. What I do have is another one under this VID/PID:

This only happens when there is blackmagic probe connected.
