Catalina install wow classic

Hello guys, I have troubles when I try to install the battle.net-setup in my mac with Catalina OS because the app is 32 bits and Catalina needs 64 bits. I see a lot of people playing with Catalina, could you tell me how I can install wow classic in Catalina?
Thanks

Hey Shune,

When extracting the ZIP file for the Blizzard Desktop App, please be sure to use the default archive utility from Apple instead of any third party software. The installer should work on Catalina.

If the problem persists after the above instructions, please provide a secreenshot of the error. Example: imgur*com/abc123

Thank you for your response.

Hey there Shune,

Thanks for letting us know about this. We’ve actually gotten a couple more reports of this, but most players are able to run the game on Catalina and we don’t run into this error when we test it on Catalina either. For this problem, I suggest submitting a ticket with your system profiler file attached. We can use that to try to determine why you’re receiving this error.
