Depending on your version of Windows, you uninstall Essentials from:
Control Panel > Programs, and clicking the Uninstall option for the selected program,
or,
Settings > Apps & features, and clicking Uninstall for the selected program.
The applicable components to uninstall are:
Geocortex Core.
Geocortex Essentials, which includes tools and REST API.
Geocortex Identity Server.
If you used the Collaboration feature, Geocortex Collaboration is also in the list of programs for uninstallation.
If you installed Geocortex Analytics or Geocortex Optimizer for use with Essentials, review the uninstallation information in their respective Installation Guides.
The number of Essentials components installed on a server depends on whether you installed Essentials using the Typical or Custom installation options. The Custom option allows you to install a subset of the components.
When you uninstall the software, any files that were not installed with the software remain on the server's storage drive, such as site configuration files and log files. The Core Data directory remains on the server so that if you reinstall Essentials, the existing data and data settings can be used. The default installation location for the Data directory is:
C:\Program Files\Latitude Geographics\Geocortex Core\Data
If you do not reinstall Essentials, you can delete the Data directory.
Essentials uses Internet Information Services (IIS).
The default location is C:\inetpub\wwwroot. The files and folders created here include:
Geocortex folder
a folder for each installed viewer template (optional)
By default, the HTML5 Viewer is deployed to the Html5Viewer folder and the Silverlight Viewer is deployed to the SilverlightViewer folder.
proxy and cross-domain files (optional)
By default, the files created are called clientaccesspolicy.xml and crossdomain.xml.
In some cases you may want to manually remove these files and folders after uninstalling Essentials.
When you use the Post Installer to deploy the Essentials web applications to IIS, it creates the default configurations shown below.
Geocortex Essentials REST API:
/Geocortex/Essentials/REST
EssentialsAppPool4
ApplicationPoolIdentity
Geocortex Essentials Manager:
/Geocortex/Essentials/RestManager
EssentialsAdministrationAppPool4
ApplicationPoolIdentity
Geocortex Identity Server:
/Geocortex/IdentityServerIdentityServerAppPool
ApplicationPoolIdentity
In addition to removing the C:\inetpub\wwwroot\Geocortex folder, each viewer template folder, and the proxy and cross-domain files, you may want to remove the application pools from your website within IIS Manager. For more information, see Manage the Essentials Web Components.
