How to run WinCOM on the Macintosh

I will probably not further develop MacCOM because I do not have the time and energy to do it. Furthermore, MacCOM is using the Carbon API which will not be supported by a future version of OS X, and then all time invested in MacCOM will be for nothing.

But there are several possibilities to run WinCOM on the Macintosh:

If you are already using a virtual Windows like VirtualBox, VMWare Fusion or Parallels Desktop, then simply run WinCOM there. (VirtualBox is free of charge, the other ones cost something. And you need a Windows license.)

If you have already installed CrossOver, then install WinCOM with CrossOver. I no longer have CrossOver installed. But as I remember, you simply have to tell CrossOver that you want to install a program and that you have an installation program. Then run the downloaded 32WCOM51.exe. (CrossOver costs 60 US$ but does not need Windows.)

Otherwise you can run WinCOM with WINE which is free of charge and does not need Windows. To install WINE and WinCOM, do the following:

  • Download the latest 1.6.x version of (not WineBottler) from If you get some advertisement, wait a few seconds and then click "SKIP AD". (Do not download version 1.4.1.x or 1.7.x because with them WinCOM will not work properly.)

    If you cannot download from, you can download it from but it may not be the latest version.

  • Open the downloaded file and move Wine to Application.

  • Download 32WCOM51.exe. Then right-click on the downloaded 32WCOM51.exe and choose "Get Info". There make sure that it says "Open with: Wine". If it does not say that, then make Wine the default application to run .exe files. Then double-click on 32WCOM51.exe to install WinCOM (choose "Run directly in ...") and uncheck all checkboxes except "Install the program files in following folder".

    When you run an .exe file the first time, several dialog boxes are shown. You can just close them all except the box that says "Run directly in ...". In that box click "Go".

If you are freshly installing WinCOM then 32WCOM51.exe installs WinCOM in C:\COM which on the Mac is "Wine Files/drive_c/COM" in your home folder. This may not be a good location for WinCOM, especially if you have already installed MacCOM. If you already have installed MacCOM, then you should install WinCOM in the MacCOM folder. Otherwise I suggest to install WinCOM in the folder "COM" in your home folder.

To install WinCOM in a certain folder, at "Install the program files in following folder" write "Z:" followed by the full path of the desired folder. For example if you want to install WinCOM in /Users/yourname/COM, then enter "Z:/Users/yourname/COM" (without the quotes, and replace "yourname" with the actual name of your home folder). Then you can run WinCOMx.exe in that folder.

You can also download and install a dictionary after you have run WinCOM once.


In WINE and thus in WinCOM the driver letter of the Macintosh hard disk is Z:

Instead of pressing the Alt key (as done in Windows), you have to press the Cmd (Apple) key. For example Cmd-N for a new text.

If the font in dialog boxes is too small, then, if not yet running, start Wine (in Applications) and click on the wine glass in the menu, there click on "Configuration" and in the "Graphics" tab increase the screen resolution. And in the "Desktop Integration" tab you can configure different sizes, like the font size in menus. Then restart WinCOM.
