|Default Settings - for the Designer Launcher and Vision Client Launcher|
|Property Setting||Description||JSON Name|
|Timeout||Maximum number of seconds allowed for any Gateway communication. Any communication that exceeds this amount will cause the Launcher to abort and try again (if multiple retries are configured).|
The number of times the Launcher will to attempt to contact a gateway when launching an application. Available values are:
|Initial Heap||Amount of heap memory to be allocated to the application on startup.|
|Max Heap||Maximum amount of heap memory allocated to the application.|

Launcher JSON Configuration Files
The settings for each launcher are stored into a configuration file.
On Window's systems, if the launcher was installed under "all users", then the configuration files are located in directories under:
In either case, each type of launcher gets its own JSON configuration file. Launcher and application settings can be modified directly from this configuration file. In addition, some administrative settings are only available in the JSON configuration file. Configuration changes must be made while the launcher is closed. Notable settings are listed below.
Determines if users are able to make changes to the launcher from the GUI.
Set to true to disable the launcher's Settings menu, prevent users from managing any application from the GUI, and remove the ability to add new applications from the GUI. Defaults to false.
When a launcher attempts to launch an application, it checks the gateway version against the launcher's download version. If the launcher has not been updated within a set number of gateway updates versions (see
Setting this setting to false will disable this update check. Disabling this setting is discouraged, as newer launchers could have beneficial features or security updates.
|Dictates the number of revision differences before a launcher will prompt the user to upgrade. Defaults to 3, meaning 3 minor version updates (for example, 8.1.0 to 8.1.3 would trigger the update prompt, but 8.1.0 to 8.1.2 would not).|
The launchers are able to trust certificates from each Gateway. Normally this is an automated process: if you launch an application from a host Gateway that requires the use of Security Certificates, the launcher will attempt to retrieve the certificate details, and ask you to trust the certificates. If you have certificates from the gateway, you can manually add them to to the launcher from the Trusted Certificates tab of the Launcher's settings by clicking the Add icon.
When the launcher is aware of security certificates, you can use the Trusted Certificates screen to delete or export the certificates with the Delete icon and click the Export icon, respectively.
The directory where the Trusted Certificates are stored is under:
When the Gateway's SSL certificates are signed by a recognized Certificate Authority, no additional configuration is required on the launcher.
There is a "three dot menu" on the applications in each of the launchers and Perspective Workstation. When you click on the three dots, a dropdown list appears. There are five options available.
