I am working with Arduino on 2 PC:s, one win 10 standard and one win 10 pro. Arduino Uno-family components works well on both.PC:s. But ESP 8266 NodeMCU is reconised only on the standard Win 10 PC. On the PRO I get the error "Board nodemcuv2 (platform esp8266, package esp8266) is unknown". The card is installed OK, Arduino reloaded etc. but nothing helps. Anybody have any idea of what to do to get it work on Win 10 PRO?

Have you loaded the board definition on the Win10Pro PC?

The "Board ... is unknown" error occurs when a Boards Manager installation of a different version of a hardware package fails to completely uninstall the previous version. Here's how you solve it:
  • Click the link on the line following File > Preferences > More preferences can be edited directly in the file. This will open the Arduino15 (or similar name depending on OS) folder.
  • Navigate to the packages/esp8266/hardware/esp8266 folder.
  • You will see two folders. One is named by the version of the package you currently have installed, the other is named by the version of the package you previously had installed. Delete the folder with the previous version name. Please be very careful when deleting things on your computer. When in doubt back up!
