How to install ERA 3 mods



  1. Anna Rodd

    Can you help me conquer Era Launcher or how else can I add all of these mods on Mac? I installed Homm 3 via Porting Kit and works fine together with the HD update I guess, but I can’t seem to find the right way to put those mods in. I make them work via wineskin and seem to choose the right directory for the install, the installation process goes fine without any errors (era launcher that helps install stuff worked fine), but h3era.exe doesn’t work, mop version seems to be just normal old version of homm3 without any changes. So I must be doing sth wrong.

    I know these things aren’t made for Mac and everything I’m trying to do at this point is just amateur will to play the game with new tweaks, but maybe you know how to make this work. Thank you in advance

      I don’t have a Mac, but I would try to install them on Windows and then port the installation to Mac, or Linux if I were using Linux.

      Alternatively, gaming on anything other than Windows is a pain, modding, even more of a pain so you may have to either give up on this or go back to Windows.

      I heard some people say Parallels works on ARM-based Macs now, so you can try that.

  2. Javier

    is this mod compatible with the third upgrades mod?
    or should I choose which one stays?

      Hi Javier, they are not compatible, please do not mix them.
      You only have to choose one.
