      # WiX 3.x candle.exe/light.exe are 32-bit. A runner running as SYSTEM has
      # %LOCALAPPDATA% = C:\Windows\system32\config\systemprofile\AppData\Local,
      # and Tauri caches the WiX toolset there. WOW64 redirection then sends a
      # 32-bit process reading C:\Windows\System32 to C:\Windows\SysWOW64, where
      # that directory does not exist - so candle.exe cannot see its own folder,
      # the CLR fails to start, and Tauri reports only "failed to run
      # candle.exe". The real error is 0x80131700, visible in the Application
      # event log as ".NET Runtime ... could not be started".
      #
      # Verified on our runner: candle.exe -? exits 0 from C:\wixtest and
      # 0x80131700 from the systemprofile path - same identity, same binary.
      #
      # Pointing LOCALAPPDATA outside System32 sidesteps redirection entirely,
      # and is harmless on a runner that already runs as a normal user.
