I am getting error "Port 9000 is already in use error during installation"

Introduction

Leapwork Controllers runs at port 9000. Before installing Leapwork to a machine, the Leapwork installer checks the availability of port 9000.

The "Port 9000 is already in use" message is shown due to the following reasons:

• An earlier version of Leapwork is using port 9000.
• Another program/application is using port 9000.

Below popup is shown during installation if the port is already in use.

Resolution

The above-mentioned issue can be resolved in the following ways:

1. If an earlier version of Leapwork is using port 9000: Uninstall Leapwork and then re-install. To uninstall Leapwork, do the following:

• Open a run box by pressing the keys: .
  • Type Control Panel and press Enter.
  • Select Programs – Uninstall a program and find Leapwork in the list of installed programs.
  • Right-click Leapwork and select Uninstall.
  • Post uninstall, try installing the latest version of Leapwork.

2. In case another application is using port 9000: Try installing the latest version of Leapwork and update the port number to a new value during the installation (Example: Update Automation Controller port to 9001 as shown below).
