Installation on Windows


  1. Make sure the correct Java version (see Download page) is installed in C:\Program Files\Java
    (for a 32 bit pc in C:\Program File (x86)\Java)
  2. If ATM is already installed the program must be stopped before installing a new version
  3. Click on the downloaded file to start the installation
  4. Preferably install ATM in C:\Program Files\AncestorTreeManager

Note: If ATM is installed in C:\Program Files\AncestorTreeManager but previously in C:\AncestorTreeManager then the old version can be removed manually.


If the installer cannot find the correct Java version, the error message below will appear, where <version> is the minimum required version number. For "Java Runtime Environment" read "Java SE Development Kit".

Below is an example of a message indicating that the Java version must be a minimum of 17 (seventeen-point-zero) and a maximum of 17.100 (seventeen-point-hundred):

If it is not possible to install ATM and there is an indication that this may have to do with security or rights, then enter the exact text of the notification with Google. You will often find clues to help solve the problem.
An example of such a notification:

Starting the program

From the Start Menu or the desktop shortcut:

If you regularly work with different files, you can create your own shortcut for each file.

  1. Make a copy of the shortcut on the desktop
  2. Right-click on the newly created shortcut
  3. Select Properties
  4. The Target field on the Shortcut tab can be modified. Content of this field:
    C:\Program Files\AncestorTreeManager\bin\AncestorTreeManager.exe
    Change this for automatic loading of a file into:
    C:\Program Files\AncestorTreeManager\bin\AncestorTreeManager.exe "C:\Path to\Smith.atm"
  5. On the General tab, the name of the shortcut can be changed, e.g. to ATM Smith


So far I have not been able to find a way to officially register ATM under Windows after installation. As a result, removal is not possible in the standard way.

From version 9.2 an Uninstaller is available, located in the program folder. Clicking on Uninstaller.exe will remove all files except the program folder itself. This is due to a technical glitch of Windows. If the folder is empty, it can then be deleted manually.
