https://devzone.nordicsemi.com/f/nordic-q-a/42999/nrfgo-programming-nrf51-with-dev-kitHello, I am trying to program a nRF51 chip with a dev kit. When I install the base nRFGo Studio, it is able to detect the board but it won&#39;t read the chip because it is out of date. If I uninstall and reinstall and not install the command line toolsen-USTelligent Community 13Fri, 25 Jan 2019 12:56:03 GMThttps://devzone.nordicsemi.com/thread/167918?ContentTypeID=1Fri, 25 Jan 2019 12:56:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2f382c89-ae78-4e47-bfeb-3d95eaa380adVidar Berg<p>Hello,&nbsp;</p> <p>Please try to program the chip through the Programmer app in <strong><a href="https://www.nordicsemi.com/Software-and-Tools/Development-Tools/nRF-Connect-for-desktop">nRF connect desktop</a>&nbsp;</strong>or with nrfjprog bundled with the command line tools. The programmer app replaces nRFGo studio which has not been&nbsp;maintained for while now.&nbsp;</p> [quote user=""] It auto installs to C:/program files (x86) while the command line tools defaults to&nbsp; C:/program files.[/quote] <p>&nbsp;I may help to uninstall the 64 bit version and install the 32 bit version of command line tools instead.&nbsp;</p><div style="clear:both;"></div>
