Just did a clean new install of B4A on a brand new Windows 10 machine using the default select boxes. The Google USB Driver install failed with:
B4X:
[===================================== ] 93% Unzipping... usb_driver/amd64/WUDF
Warning: File C:\Users\username\.android\repositories.cfg could not be loaded.
Some people on the interner claim you have to create this file yourself before installing the SDK. Weird. It's not linked to B4a but it might scare inexperienced users.
