To be able to successfully install and use WFP, your computer system must meet the system requirements detailed under Specifications at the Wordfast Pro webpage.


Windows installer icon
To install WFP in Windows[1], follow these steps:
  1. Double click on the downloaded MSI file and follow the installation wizard.
  2. Make sure to install for “all users”.

That's it! Next, you may want to activate the license in WFP on your computer or check if your license is activated in WFP.

If installation fails, see some advice on why Wordfast Pro fails to install in Windows.


Mac installer icon
To install WFP in MacOS[2], follow these steps:
  1. After downloading Wordfast Pro, double-click on the downloaded installer to open the installation wizard.
  2. Drag the Wordfast file onto the Applications folder.
  3. Mac installer window

    If you get a message saying “An older item named Wordfast already exists in this location. Do you want to replace it with the newer one you’re moving?”, click on Replace.[3]

  4. Open a Finder window and, on the lefthand column, click on the Eject button under Devices to close the installer.

That's it! Next, you may want to activate the license in WFP on your computer or check if your license is activated in WFP.

NB! If you are running macOS 12.7 or newer and see the following warning: “Wordfast” can’t be opened because Apple cannot check it for malicious software. This software needs to be updated. Contact the developer for more information.

Please read the following for a workaround that will let you install Wordfast Pro:

Watch the following video to see how to do it:


Download the .tgz archive from our website and unpack it. You can start Wordfast Pro directly from the unpacked folder by double-clicking the wordfast executable file. It is a good idea, however, to move the installation folder to where your other installed apps are.

NB! If Wordfast Pro fails to start (is stuck) after double-clicking the executable, then it is likely that you are missing the required libgconf-2-4 package. If that's the case, stop Wordfast Pro (kill the process) and, if you are running a Debian-based distro:

sudo apt-get update

sudo apt-get install libgconf-2-4

Then try starting Wordfast Pro again.

If it still won't start, try disabling Wayland. To do this, you need to edit the configuration file:

sudo nano /etc/gdm3/custom.conf

Uncomment (remove # from) the line containing:


The save the file (ctrl + x and after that y ('yes') or another key for non-English and finally Enter).

Reboot your computer.

Note: On Debian, the filename is "/etc/gdm3/daemon.conf", on Ubuntu and possibly some other Linux distributions it is "custom.conf". The best way to find out is to navigate to the gdm3 directory and check name of the .conf file.

If you are using Arch or an Arch-based Linux distro, where libgconf-2-4 is not available in the repositories, you need to run:

yay -Syy gconf

If using Fedora/Red Hat:

sudo dnf install GConf2


  1. WFP version 5.10 and above require a 64-bit version of Windows
  2. MacOS 10.11 or newer is required.
  3. If you click on Keep Both, you will have multiple installations of the same software and likely get confused. To be on the safe side, you can always keep previous versions of the installer file in case you need to revert back to a previous version.
