Change, repair, or remove PI Web API

You can change, repair, or remove a PI Web API installation in two different ways.

1. If the version of PI Web API that you are installing is the same as one that is already installed, run the PIWebApi.msi file of the installed version directly.

2. Select the PI Web API program from the list of installed programs in Control Panel > Programs and Features.

   You can select Change, Repair, or Uninstall.

   • Change

     Select this option to change one or more installation settings. The change options are the same as the installation options. You cannot change the installation or destination folder. To change the installation or destination folder, you should uninstall and then reinstall PI Web API.

   • Repair

     Select this option to repair problems with the PI Web API installation, such as restoring missing files or registry values. You cannot change installation settings using this option.

   • Uninstall

     Select this option to remove the PI Web API. Uninstalling the product does not remove:

     • Any SSL certificates that were created during the installation process.

     • The binding of the selected SSL certificate to the port used by PI Web API in the Windows HTTP service’s configuration.

     • The URL reservation for PI Web API in the Windows Kernel routing table.
