Task manager is saying it's the legacy edition, which is weird as I did not download it. It seems it must have been auto downloaded when I did the update? But when I try to open the game it tells me that I am missing files and need to download the legacy edition. I just download the legacy edition to see if that will give me the option to change it to 64bit but the option is still not showing up in advanced launch options.
I am now able to open and run the game as legacy edition, but I'm not seeing anyway to run the 64bit version.
Update: I have now gotten it to work. For anyone with a similar problem, trying using the repair option in the setting menu. Since doing that the option field for "When launching this game" has now appeared and I am able to run the 64bit version.
