What does the Installation Error 1603 mean?


The following table summarizes the different possible problems that may prevent the Collector MSI package from being installed:

  • You don't have the administrative privileges on this machine to install the Nexthink Collector. Make sure you are using the correct credentials with local administrative privileges.

  • Your Operating System (OS) is not compatible with this version of the Nexthink Collector. Make sure you have chosen the right Collector package for your OS.

  • The Nexthink Collector is not compatible with your OS architecture. Make sure you are using the installer that belongs to your OS architecture.

  • A newer version of the Nexthink Collector is already installed. Uninstall it first if you want to proceed.

  • The Nexthink Collector service is marked for uninstall. Reboot your computer and try again.

  • When installing the driver with a deployment tool, the installation process fails and the following error is raised: "For this MSI package to be installed, Windows Installer must be run from within an interactive session." This issue only occurs if the user installing the Collector package is not a LocalSystem user.
