Installing TestComplete in Silent Mode

Applies to TestComplete 15.52, last modified on June 06, 2023

In some cases, you may need to install TestComplete in silent mode. In this mode, the installation is performed automatically without any user interaction. For example, you install TestComplete in silent mode if you need to automate the installation procedure or deploy TestComplete on multiple computers on your network.

You can install TestComplete in silent mode via command-line arguments.

Check the silent installation results

In silent mode, the installation wizard shows no messages. You can use the -Log command-line argument to configure the installation to create a log file and write all the progress information to it. After the installation is over, you can examine that log file to learn what was happening during the installation and check the installation result.
