This page shows step-by-step how to install Ancestris on a Windows system.

The sections below are independent and do not all need to be done.

Screens shown might look different from those of the current Ancestris web site or the current Ancestris software version.

Knowing which Java version you use

Java Control Panel

Open the Windows Control Panel and then the Java Control Panel.

On its General tab, click 'About' to check the installed Java version.

Command prompt

Alternatively, these steps let you identify which version of Java is running on your system.

1 - Open a Windows PowerShell window and enter CMD or open a Command Prompt window.

2 - Type java -version at the prompt. You will obtain a display as below, which shows that Java Version 8 (aka 1.8) 64-Bit is installed. Otherwise, it means java is not installed. Follow these instructions to install it.

java version "1.8.0_221"
Java(TM) SE Runtime Environment (build 1.8.0_221-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.221-b11, mixed mode)

3 - Type exit once or twice to close the command window.

2/6 - Extract the Ancestris file
  • Ancestris does not need to be installed as it runs directly from its .exe file.
  • So right-click the downloaded file, choose 'Extract All' and select a destination folder where the .exe file can run.
  • On Windows 7, unzip into the C:\Program Files folder otherwise Ancestris won't run.

3/6 - Check the Ancestris file to run
  • In the destination folder, open the ancestris folder and then the bin folder; there the ancestris64.exe file will run Ancestris on a 64-bit system, while the ancestris.exe file will run it on a 32-bit system.

If Ancestris does not start, it might be related to a Java version issue. You may have to swap the Java version.
Please follow these instructions.
