The Windows Coach 7.4 installation has been modified to not reset the Author key to the default value after update. This means that a file, which contains this Author key, will not be overwritten during Coach Installation. Unfortunately for installation of Coach 7.4 on some systems a direct upgrade (installation when an older version of Coach is installed) does not work correctly. In such situation, the file is deleted and not replaced by the new one, and you get an error message Cannot read Author key file. It may be missing or corrupt. There are two ways to solve this problem:
1. First uninstall the older version of Coach and after that install the new Coach 7.4, or
2. Run “Program and Features” repair.

This message appears when there is a program e.g. antivirus program, which blocks access to the User’s Documents folder. To solve this problem give Coach 7 access to this folder.



Coach 7 has the following system requirements:

For Windows

  • Windows 7 or newer;
  • Pentium 4 / 2,4 GHz processor or newer;
  • 300 MB hard disk space;
  • 512 MB RAM (1 GB recommended).

For Mac

  • OS X 10.11 El Capitan or newer;
  • 300 MB hard disk space;
  • 512 MB RAM (1 GB recommended).

More information about Coach 7 can be found in the installation guide and the dedicated Coach 7 page.

No, a special server-client network installation similar to what was available for Coach 6 is not possible for Coach 7. This method is no longer necessary. Coach can be installed safely to a shared network location, and users can start the application by opening the executable from there. At first launch, Coach will copy several configuration files to the user’s local data (e.g. CoachLocal.ini to AppData\Local\CMA\Coach7). You can edit Coach.ini from the installation folder to modify the paths to several important locations, such as the license file. See the Installation Guide for more information.

You can add multiple options to an MSI-installer. Consult the software Installation guide for more details. Use the options LICENSENAME and LICENSECODE to set these parameters for the entire installation process. When installing to a network location for shared access, the location of the license file can be fixed by modifying Coach.ini. It is still necessary to run Coach once after installation to generate the license files in the default location.

Make sure you do the following:

  1. Download and install the CMA certificate.
  2. Update the root certificates of Microsoft and VeriSign. This is usually not necessary if you use a fully updated version of Windows.

Please consult the Installation guide to troubleshoot any installation related problems. Follow the installation steps carefully. Use the ‘Ask a question’ form if the installation problems persist.
