Is there any way for the game to know if it is running the 32-bit or the 64-bit exe?

The SteamUtils wrapper I made in connection with a previous question in working, but only in 64-bit mode. Almost no one plays my game in 32-bit as far as I can tell. I’d like to just not use SteamUtils if the game is running in 32-bits. Is there any way for the game to know which version it is?

I’m adding an option to my 32-bit startup command ?win32=true. If that’s on there, the game won’t create my SteamUtils wrapper. I just need to make sure to update the Steam launcher commands.
