# Viewing current license information

To view licensing information for Trimble Access apps installed on the controller, tap and select About.

The About screen shows software licenses that are in use by the controller or by the signed-in Trimble Access user.

If the About screen does not show the licenses that you expect or need, contact your organization's License Administrator. This person is someone within your organization who uses the Trimble License Manager web app to administer licenses to users in your organization. For more information, see the Trimble License Manager Help.

User licenses

User license types shown in the About screen include:

- Trimble Access subscription licenses

- Related subscription licenses downloaded to the controller (for example, Trimble Catalyst Survey subscriptions)

- Related subscription licenses assigned to the current user (for example, Trimble Connect subscriptions)

  A Trimble Connect Business subscription allows you to create more projects and synchronize data with more projects than a Trimble Connect Personal subscription. If you are using a perpetual license for Trimble Access then the controller must have a current Trimble Access Software Maintenance Agreement for you to be able to synchronize Trimble Access data with the cloud.

By default, Trimble Access and Trimble Catalyst Survey subscriptions are locked to the controller until you sign out. You must sign out on the current controller before you can use your subscriptions on a different controller. If you don't always use the same controller, you can configure the software to release your subscription licenses automatically when exiting the software, or to prompt you to sign out and release your subscription on exit. To do this, select the appropriate option from the When exiting the software field in the About screen.

Controller licenses

User license types shown in the About screen include:

- Controller licenses:

  - Trimble Access perpetual licenses

  - Trimble Access demo/trial licenses

The Software maintenance expiry field applies only to perpetual licenses and shows the expiry date of the Software Maintenance Agreement.

If you are using a perpetual license for Trimble Access, then the controller must have a current Trimble AccessSoftware Maintenance Agreement for you to be able to synchronize Trimble Access data with the cloud or to update the Trimble Access software.

If you or your organization's License Administrator has recently renewed or extended your controller's Software Maintenance Agreement, you must run the Trimble Installation Manager software on the controller to download and install the new software maintenance file. Once this is installed, the Software maintenance expiry field shows the new expiry date.

GNSS receiver option subscriptions

Information about GNSS receiver options provided by subscription are not shown in the About screen because that subscription is specific to an individual receiver and is not locked to the user or the controller.

If you are using a receiver that has options provided by Trimble GNSS subscription (such as an R750 or R780 receiver), tap and select Instrument / Receiver settings to view information about the subscription.
