Changing from 32 to 64 bit

I did not realize i clicked on 32 bit and i ant to play 64 I have uninstalled and that was no help Game goes right into menu without any choice Any help be appreciated

Edit: Deleted.

I misread the question and explained how to run in 32 bit.

thank you its a steam game

Do the above and then select Play Grim Dawn x64 from the drop down.

If you have the game on GOG Galaxy then click on the icon next to Play and I assume you’ll find the option here

Mine’s already set for x64 so it doesn’t show that in Additional executables.

GoG launches x64 by default without asking anything.
