In the standard Windows (Win32) version of the Arduino IDE, theme settings like syntax coloring can be modified in C:\Program Files (x86)\Arduino\lib\theme\theme.txt.

For the Windows Store app version of the IDE the theme files are stored in protected app storage space.

Is there a simple/safe way to change theme settings for the Windows Store app version of the IDE without messing up security settings and inadvertently lowering Windows security?

(It would be easier and better if theme settings could be moved to the ArduinoData user folder where preferences.txt is stored.)

    Don't use the Windows App Store version? – Majenko Apr 24 '17 at 11:16
  • I assume not using the Windows Store version is not an option (because that's the easiest answer). An alternative that might work (if you have admin access) is to use Junction.exe to create a symbolic link between a writeable directory and where the themes are stored. But changing the perms on that directory is going to be easier. – Code Gorilla Apr 24 '17 at 11:54

There is a way, but not necessarily simple. You basically need to replace the current theme files with the new ones.

  1. Rename {Arduino IDE installation folder}/lib/theme to {Arduino IDE installation folder}/lib/theme.bak
  2. Download https://github.com/jeffThompson/DarkArduinoTheme/archive/master.zip
  3. Copy the theme folder from the downloaded file to {Arduino IDE installation folder}/lib
  4. Restart the Arduino IDE if it's running.
