Re: After Catalina Installed on Mac -Plants vs Zombies Game of the Year won't launch

@Player_921t69ev  Sorry that no one replied to you sooner; it looks like your post was recently moved here from somewhere else.

Plants vs. Zombies is a 32-bit app, and Catalina is 64-bit only, so the game won't run in Catalina.  I haven't heard anything about a 64-bit update, so it may be that this game will never run in Catalina or any subsequent version of macOS.

The only way to play would be to use another operating system.  Aside from playing on a different computer, you could install Windows through a virtual machine (e.g. Parallels) or Bootcamp.  Or, if you have at least temporary access to a Mac still running Mojave or earlier, you could use that computer to install Mojave onto an external hard drive.
