Hello support team Have you tested the nRFgo 1.15 x64? usually x64 installs in Program Files this installs in Program Files (x86) any reason why? I had to recover my PCA10001 V2.0 after a bad programming (the core Cortex-M0 was not found) and the last nRFgo update (1.15) could not recover it. I had to reinstall nRFgo 1.14 x86 version and my board is working fine again. Thanks
