Command-line build 64-bit

I’ve made a batch code that automatically creates a build (for Windows). However, this build is by default made in 32-bit. We used the code from the manual. I cannot find any information on how to set whether you want the command line code to produce a 32-bit or a 64-bit version. This does work manually, but the idea is that it’s produced by the batch file. Can anyone help?

1、build 32bit windows standalone player with -buildWindowsPlayer
2、copy “Program Files (x86)\Unity\Editor\Data\PlaybackEngines\windows64standaloneplayer\player_win.exe” to your app dir, and rename it to YourAppName.exe。
3、copy “Program Files (x86)\Unity\Editor\Data\PlaybackEngines\windows64standaloneplayer\Data\Mono\mono.dll” to YourAppName_Data\mono.dll
4、use another tool to change the default icon of YourAppName.exe
5、enjoy it!
