REQUIRED: It is always important to backup your files on the computer before you make changes to any program. This includes MasterCook.

This installation file is designed to update an existing installation of MasterCook 2020 as well as a stand-alone new installation. Therefore, you can delete the previous download installation file and keep the new one going forward.

  • UPDATING CURRENT MASTERCOOK 2020 INSTALLATION: If it detects a current installation of MasterCook 2020 on the computer, it will update the program files only and not touch the user files (preference settings, My Cookbook, etc.) Please do NOT change the path during the installation. The installer knows where the program is currently installed and will update there. (If you change the path, it will create new user folders & files at the new location and will no longer use the old location.)
  • NEW MASTERCOOK 2020 INSTALLATION: If MasterCook 2020 is not currently installed on the computer, it will fully install the program onto the computer.


  1. Make sure you have current backup copies of your MasterCook files on the computer before you install.
  2. Download the installation file first and do not open it yet. Allow it to fully download to your computer and save a copy of that file to a location where you keep all important files that you backup regularly. This will prevent you from having to pay for a replacement in the future.
  3. Restart the computer so nothing is running and can interfere and corrupt the installation and proceed with installing.
  4. If your antivirus uses community feedback to determine if files are safe to install, the MasterCook update will be too new for others to know and report the MasterCook installation file as being legitimate. Therefore, your antivirus may block you from downloading or installing the file. Review the documentation that comes with your antivirus for instructions with the error message it is reporting.

Known Issues:
